HDTV CLOCK SYNTHESIZER CLOCK SYNTHESIZER IDT™ HDTV CLOCK SYNTHESIZER 2 MK2716 REV G 051310 Pin Assignment F REQUENCY SELECT TABLE Pin Descriptions External Components Decoupling Capacitor As with any high performance mixed-signal IC, the MK2716 must be isolated from system power supply noise to perform optimally. A decoupling capacitor of 0.01µF must be connected between VDD and GND on pins 2 and 3. It must be connected close to the MK2716 to minimize lead inductance. Pin 5 can be connected to pin 3. No external power supply filtering is required for the MK2716. Series Termination Resistor A 33Ω terminating resistor can be used next to the clock outputs for trace lengths over one inch. Crystal Load Capacitors The total on-chip capacitance is approximately 18 pF . A parallel resonant, fundamental mode, AT cut 27 MHz crystal should be used. The device crystal connections should include pads for small capacitors from X1 to ground and from X2 to ground. These capacitors are used to adjust the stray capacitance of the board to match the nominally required crystal load capacitance. Because load capacitance can only be increased in this trimming process, it is important to keep stray capacitance to a minimum by using very short PCB traces (and no vias) between the crystal and device. Crystal capacitors, if needed, must be connected from each of the pins X1 and X2 to ground. The value (in pF) of these crystal caps should equal (C L -16 pF)*2. In this equation, CL= crystal load capacitance in pF . Example: For a crystal with an 18 pF load capacitance, each crystal capacitor would be 4 pF [(18-16) x 2] = 4.

These ratings, which are standard values for IDT commercially rated parts, are stress ratings only. Functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over the recommended operating temperature range.
