4.2 Function Settings
4.2.1 Output Termination Detector
On power up or when PEN becomes true, the output resistance is set to 2K ohms, and the input resistance is set to 200K ohms. The device continually looks to detect an external 50 ohm termination resistor on a per channel basis. If no 50 ohms is detected in the first 5ms of time, the channel is continually polled with 5ms detection cycle until detection occurs.
4.2.2 Signal Detector
The signal detector is used to detects whether the RX terminal has any valid input signal or not. If the input differential signal is lower than Vth-, then it has no output; if the input differential signal is higher than Vth+, then ReDriver will output the received signal.
4.2.3 Power Enable Function
One pin control or I2C control, when PEN is set to low, the IC goes into power down mode, both input and output termination set to 200K and 2K respectively. Individual Channel Enabling is done through the I2C register programming.
4.2.4 Equalization Setting
BST[3:0] are the selection pins for the equalization selection for each channel.

Application/Implementation Note Information in the following applications sections is not part of the component specification, and does not warrant its accuracy or com- pleteness. Customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality.
7.1 Source Application
PI3HDX1204B1 is designed to accept AC-coupled as well as DC-coupled main link signals. When a dual-mode DP source is connected to the input of PI3HDX1204B1 in a source application, AC coupling capacitors must be placed at the input side.

7.1.1 ESD Protectors on Output TMDS
As 8kV contact ESD is commonly required, ESD protectors are implemented at the output TMDS pins of PI3HDX1204B1 for source
7.1.2 Extra Component for Rise/fall Time Control
Per HDMI2.0 specification, rise/fall time of TMDS clock is kept at minimal 75ps while that of TMDS data is decreased to minimal 42.5ps if data rate is between 3.4Gbps and 6Gbps. Figure 7-2 HDMI2.0 Trise/fall Requirement PI3HDX1204B1 is designed to meet the rise/fall time of TMDS data. If output trace length is short, maybe 1” only, common-mode choke or external inductor can be considered for slowing down the rise/fall time for TMDS clock of PI3HDX1204B1. VCC VCC VCC

7.1.3 Leakage Blockage for VOFF Test
When performing VOFF test specified in HDMI 1.4a Compliance Test Specification, each output TMDS of PI3HDX1204B1 will be pulled to 3.3V via an external 50Ω resistor. In this case, current will pass through an internal ESD protector at the output TMDS pin of PI3HDX1204B1 and leakage will be found at VCC pin of PI3HDX1204B1. Figure 7-3 HDMI VOFF Test Setup Figure 7-4 HDMI VOFF Requirement To avoid this leakage, AP2151A power switch can be employed between the main 3.3V supply on a system and the VCC power plane of PI3HDX1204B1. Below is an example borrowed from an evaluation board schematic. Figure 7-5 Power Distribution Switch Example 7 .2 Sink Application PI3HDX1204B1 can also be employed in a sink application as it offers a range of equalization setting.

7.4.2 Output Trace Length
To fulfill minimal 75ps rise/fall time requirement of TMDS clock, 1.5 – 4.5” TMDS trace length between PI3HDX1204B1 and HDMI connector for source application is recommended. This trace length varies with PCB trace width, characteristics of common-mode choke/ESD protector and connector quality. If trace width is 5 mil, 2.7 – 3.3” is recommended. Isolation space should be larger than 5 mil to minimize the crosstalk so thus jitter. Below is the PI3HDX1204B1 placement on its evaluation board. Figure 7-9 Source-side Placement near to the HDMI Connectors
7.4.3 Differential Impedance (TDR)
Layout guideline especially for high-speed transmission is critical. Please refer to PI3DPxxx_PI3HDxxx_Layout Guideline for detailed recommendations. Differential impedance test is required for both source and sink applications per HDMI 2.0 specification. Figure 7-10 HDMI2.0 Differential Impedance Requirement for Source Application

PI3HDX1204B1 Document Number DS42401 Rev 5-2 www.diodes.com Figure 7-11 HDMI2.0 Differential Impedance Requirement for Sink Application The PCB impedance immediately before and after an ESD protector must be adjusted to compensate the capacitance loading of the ESD protector. Below is an example designing RClampe0544M in PI3HDX1204B1 evaluation board. Trace impedances before and after the ESD protector are tuned to compensate the capacitance of RClamp0544M. Semtech’s layout guideline is followed. Figure 7-12 ESD Protector on PI3HDX1204B1 Source EVB
7.4.4 GND via on the Thermal Pad Area
Several GND via are “MUST” required on thermal area. The via size is 12/24 mil. Below is the thermal pad via layout recommendation. Figure 7-13 Recommended Land Patterns

PI3HDX1204B1 Document Number DS42401 Rev 5-2 www.diodes.com 7 .5 General Layout Guideline As transmission data rate increases rapidly, any flaws and/or mis-matches on PCB layout are amplified in terms of signal integrity. Lay- out guideline for high-speed transmission is highlighted in this application note.
7.5.1 Power and Ground
To provide a clean power supply for Pericom high-speed device, few recommendations are listed below:
- Power (VCC) and ground (GND) pins should be connected to corresponding power planes of the printed circuit board directly without passing through any resistor.
- The thickness of the PCB dielectric layer should be minimized such that the VCC and GND planes create low inductance paths.
- One low-ESR 0.1uF decoupling capacitor should be mounted at each VCC pin or should supply bypassing for at most two VCC pins. Capacitors of smaller body size, i.e. 0402 package, is more preferable as the insertion loss is lower. The capacitor should be placed next to the VCC pin.
- One capacitor with capacitance in the range of 4.7uF to 10uF should be incorporated in the power supply decoupling design as well. It can be either tantalum or an ultra-low ESR ceramic.
- A ferrite bead for isolating the power supply for Pericom high-speed device from the power supplies for other parts on the printed circuit board should be implemented.
- Several thermal ground vias must be required on the thermal pad. 25-mil or less pad size and 14-mil or less finished hole are rec - ommended.

7.5.2 High-speed Signal Routing
Well-designed layout is essential to prevent signal reflection:
- For 90Ω differential impedance, width-spacing-width micro-strip of 6-7-6 mils is recommended; for 100Ω differential impedance, width-spacing-width micro-strip of 5-7-5 mils is recommended.
- Differential impedance tolerance is targeted at ±15%.

8.2 Part Marking Information
Our standard product mark follows our standard part number ordering information, except for those products with a speed letter code. The speed letter code mark is placed after the package code letter, rather than after the device number as it is ordered. After electrical test screening and speed binning has been completed, we then perform an “add mark” operation which places the speed code letter at the end of the complete part number.

8.3 Tape & Reel Materials and Design
The Pocketed Carrier Tape is made of Conductive Polystyrene plus Carbon material (or equivalent). The surface resistivity is 10 6Ohm/sq. maximum. Pocket tapes are designed so that the component remains in position for automatic handling after cover tape is removed. Each pocket has a hole in the center for automated sensing if the pocket is occupied or not, thus facilitating device removal. Sprocket holes along the edge of the center tape enable direct feeding into automated board assembly equipment. See Figures 3 and 4 for carrier tape dimensions. Cover Tape Cover tape is made of Anti-static Transparent Polyester film. The surface resistivity is 107Ohm/Sq. Minimum to 1011Ohm sq. maximum. The cover tape is heat-sealed to the edges of the carrier tape to encase the devices in the pockets. The force to peel back the cover tape from the carrier tape shall be a MEAN value of 20 to 80gm (2N to 0.8N). Reel The device loading orientation is in compliance with EIA-481, current version (Figure 2). The loaded carrier tape is wound onto either a 13- inch reel, (Figure 4) or 7-inch reel. The reel is made of Antistatic High-Impact Polystyrene. The surface resistivity 107Ohm/sq. minimum to 1011Ohm/sq. max.

A0, B0, and K0 are determined by component size. The cavity must restrict lateral movement of component to 0.5mm maximum for 8mm and 12mm wide tape and to 1.0mm maximum for 16,24,32, and 44mm wide carrier. The maximum component rotation within the cavity must be limited to 20o maximum for 8 and 12 mm carrier tapes and 10o maximum for 16 through 44mm. 2. Tape and components will pass around reel with radius “R” without damage. 3. S1 does not apply to carrier width ≥32mm because carrier has sprocket holes on both sides of carrier where Do≥S1. 4. So does not exist for carrier ≤32mm because carrier does not have sprocket hole on both side of carrier.
