Video Processing Procurement Notes

Verify the specific ordering suffix, as 'T' indicates tape and reel packaging while other suffixes may denote tube packaging or lead-free configurations. Confirm RoHS compliance status, noting that non-green parts have reached end-of-life. Ensure the component meets the required ambient operating temperature range of 0 to +70 °C for your specific design environment.

Video Processing Selection Notes

Select this component when precise clock derivation from HDTV reference signals is required for audio and video subsystems. Consider the 8-pin SOIC package constraints and the need for series termination resistors on clock output traces. Evaluate power supply decoupling requirements, specifically the placement of 0.01µF capacitors near the VDD pin to minimize system power supply noise.

Video Processing Part Context

The ICS662M-03T belongs to the IDT/ICS HDTV Audio/Video Clock Source family. It utilizes Phase-Locked-Loop (PLL) technology to synthesize frequencies from a single HDTV input clock. The device is manufactured by Integrated Device Technology, now part of Renesas Electronics Corporation, targeting consumer video electronics requiring stable timing references.

Video Processing Replacement Considerations

Check for availability of the lead-free variant, designated with an LF suffix, if environmental compliance is mandatory. Verify if alternative clock synthesizers from the same manufacturer support similar HDTV input frequencies and output configurations.

Video Processing FAQ

How is the output frequency determined?

The output frequency is selected via four digital input pins (S3, S2, S1, S0). These pins utilize internal pull-up resistors and determine the specific multiplication ratio based on the provided selection table.

What are the PCB layout recommendations for optimal performance?

For lowest output phase noise, mount 0.01µF decoupling capacitors on the component side close to the VDD pin without vias. Place a 33Ω series termination resistor close to the clock output pin to minimize EMI and ensure signal integrity.
