ICS671-01

ZERO DELAY LOW SKEW BUFFER AND MULTIPLIER DATASHEET ICS671-01 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 Pb (lead) free package, RoHS compliant Clock outputs from 5 to 160 MHz Zero input-output delay Integrated x2 or x4 selections, and x5 for CLK7 Eight low-skew (<250 ps) outputs Full CMOS outputs with 25 mA output drive capability at TTL levels Tri-state mode for board-level testing Advanced, low power, sub-micron CMOS process Operating voltage of 3.3V or 5V Block Diagram VDD 2 CLKIN FBIN x2, x4, or x5 PLL S1, S0 2 Control Logic 2 GND CLK1 CLK2 CLK3 CLK4 CLK5 CLK6 CLK7 CLK8 IDT™ / ICS™ ZERO DELAY LOW SKEW BUFFER AND MULTIPLIER 1 ICS671-01 REV F 051310 ICS671-01 ZERO DELAY LOW SKEW BUFFER AND MULTIPLIER ZDB AND MULTIPLIER Pin Assignment C L K IN CLK1 CLK2 VDD GND CLK3 CLK4 S0 1 2 3 4 5 6 7 8 16 ...
