DTV, STB CLOCK SOURCE
ICS3771-18
Description
Features
The ICS3771-18 provides clock generation and
conversion for clock rates commonly needed in HDTV
digital video equipment. The ICS3771-18 uses the
latest PLL technology to provide excellent phase noise
and long term jitter performance for superior
synchronization and S/N ratio.
• Integrated Phase-Lock Loop
• Low jitter, high accuracy outputs
• 3.3 V operation
• Packaged in 16-pin TSSOP
• RoHS 6 (green and lead free) compliant packaging
• Exact (0 ppm) multiplication ratios
For audio sampling clocks generated from 27 MHz, use
the ICS661.
• Pin compatible to CY24204-3
Please contact IDT if you have a requirement for an
