ICS664-01
Digital Video Clock Source
Description
The ICS664-01 provides clock generation and
www.dactaosnhveeetr4sui.oconmfor clock rates commonly needed in HDTV
digital video equipment. The ICS664-01 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 in this
document. ICS can rapidly modify this product to meet
special requirements.
Features
• Packaged in 16-pin TSSOP
• Clock or crystal input provides flexibility
• Low phase noise supports enhanced SNR
• Lowest jitter in class at 100 ps
• Exact (0 ppm) multiplication ratios
• Power-down mode lowers power consumption
• Improved phase noise over ICS660
