© 2025 Copyright Diodes Incorporated. All Rights Reserved. PI5USB212 Document Number DS44950 Rev 6-2 www.diodes.com Overview The PI5USB212 is an USB2.0 High-Speed (HS) Signal conditioner to boost the signals and insert pre-emphasis to compensate the ISI signal loss in the channels before and after. PI5USB212 will not alter the signals of USB Low Speed (LS), Full Speed (FS), On-The-Go (OTG) and Battery Charging (BC), while HS signals are compensated. Boost/Pre-emphasis level and Receiver Sensitivity can be pro - grammed by I2C or pin mode. BOOST/PRE-EMPHASIS The BOOST pin of PI5USB212 is used to configure the level of BOOST/PRE-EMPHASIS in pin mode and initialize the corresponding register in I2C mode. Amplitude boost compensates the amplitude loss due to the long channel before PI5USB212, and pre-emphasis compensates the high frequency loss due to the low-pass long channel after PI5USB212. The four settings can be selected by an external pulldown resistor at this pin and it will be sampled a short moment after RSTN rising. BOOST Pin Connection Register Default Value Boost/Pre-Emphasis Level Setting 0 (<160 Ω) 0000 Lowest Setting 1 (~1.8 kΩ) 0101 Lower Mid Setting 2 (~3.6 kΩ) 1010 Higher Mid Setting 3 (>7.5 kΩ) 1111 Highest Receiver Sensitivity The SEN pin of PI5USB212 is used to configure the level of Receiver Sensitivity in pin mode and initialize the corresponding register in I2C mode. The three settings can be selected by connecting the pin to VCC/Floating/GND during RSTN and it will be sampled a short moment after RSTN rising. After RSTN, the pin will function as an output for HS detection.

PI5USB212 Document Number DS44950 Rev 6-2 www.diodes.com I2C Mode PI5USB212 supports 1MHz down-to-1.2V I2C for device configuration and status readback. This controller is enabled after SCL and SDA pins are sampled high shortly after de-assertion of RSTN. Otherwise, pin mode is enabled. In I2C mode, the registers can be ac - cessed by I2C read/write transaction to 7-bit slave address 0x2C.

In pin mode, CD pin is asserted high. High Speed (HS) Mode PI5USB212 automatically detects a HS connection and will enable signal compensation. In pin mode, CD and HS pins are asserted high. OTG Mode/B.C.1.2 Mode Shutdown Mode PI5USB212 is disabled when its RSTN pin is asserted low. In shutdown mode the USB channel is still fully operational, but there is neither signal compensation nor any indication from the CD or HS pin as to the status of the channel.
