Video Processing Procurement Notes

Verify the specific ordering suffix required for your manufacturing process. The standard part number may be available in tube packaging, while tape and reel options exist for automated assembly. Confirm lead-free status if RoHS compliance is mandatory, as non-green parts have reached end-of-life. Ensure the selected variant matches the required shipping format and environmental specifications before finalizing procurement.

Video Processing Selection Notes

Select this component when designing systems requiring precise clock derivation from HDTV reference signals. It is suitable for applications needing 27 MHz outputs for MPEG video processing. Consider the 8-pin SOIC package constraints and ensure PCB layout guidelines are followed to minimize EMI and optimize phase noise performance. Verify that the input frequency matches the supported HDTV standards.

Video Processing Part Context

Video Processing Replacement Considerations

Non-green versions of this part have reached End-of-Life. Verify availability of lead-free variants such as the 662M-03LF or 662M-03LFT for new designs. Check for updated documentation regarding pin compatibility and electrical characteristics when transitioning from older non-compliant stock to current production units.

Video Processing FAQ

What is the nominal output impedance of the ICS662M-03?

The nominal output impedance is 20 Ω.

How should the decoupling capacitors be placed for optimal performance?

0.01µF decoupling capacitors must be connected between VDD and GND on the component side of the board, as close to the VDD pin as possible, without using vias between the capacitor and the pin.

What series termination resistor value is recommended for a 50Ω trace?

A 33Ω resistor should be placed in series with the clock line, as close to the clock output pin as possible, to terminate a 50Ω trace.
