DATASHEET
DTV, STB CLOCK SOURCE
Description
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.
For audio sampling clocks generated from 27 MHz, use
the ICS661.
Please contact IDT if you have a requirement for an
input and output frequency not included in this
