ICS671-01 Datasheet | Renesas

ZERO DELAY LOW SKEW BUFFER AND MULTIPLIER 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.
