ZERO DELAY LOW SKEW BUFFER AND MULTIPLIER ICS671-01
IDT™ / ICS™
ZERO DELAY LOW SKEW BUFFER AND MULTIPLIER 1
ICS671-01 REV E 110409
Description
The ICS671-01 is a low phase noise, high speed PLL
based, 8 output, low skew zero delay buffer and multiplier.
Based on IDT’s proprietary low jitter Phase Locked Loop
(PLL) techniques, the device provides eight low skew
outputs at speeds up to 160 MHz at 3.3V. The part includes
a bank of six outputs running at either x2 or x4 mode, one
output running at either x2, x4, or x4 mode, and one
additional output running at either x1, x2, or x4 mode. For
normal operation as a zero delay buffer, any output clock is
tied to the FBIN pin.
IDT manufactures the largest variety of clock generators
and buffers and is the largest clock supplier in the world.
Features
• Packaged in 16 pin SOIC
