QUAD PLL WITH VCXO FOR HDTV
IDT™ / ICS™ QUAD PLL WITH VCXO FOR HDTV
Description
The ICS477-05 generates five high-quality,
high-frequency clock outputs including two reference
outputs from a low frequency pullable crystal. It is
designed to replace crystals and crystal oscillators in
most electronic systems.
Using Phase-Locked-Loop (PLL) techniques, the
device runs from a fundamental mode, pullable crystal.
It can replace multiple crystals and oscillators, saving
board space and cost.
