ICS660

ICS660 Digital Video Clock Source Description The ICS660 provides clock generation and conversion for clock rates commonly needed in digital video equipment, including rates for MPEG, NTSC, PAL, and HDTV. The ICS660 uses the latest PLL technology to provide excellent phase noise and long term jitter performance for superior synchronization and S/N ratio. For audio sampling clocks generated from 27 MHz, use the ICS661. Please contact ICS if you have a requirement for an input and output frequency not included here - we can rapidly modify this product to meet special requirements.
