DATASHEET VOLT ZERO DELAY LOW SKEW BUFFER ICS2305 The ICS2305 is a low phase noise, high-speed PLL based, low-skew zero delay buffer. Based on IDT’s proprietary low jitter Phase Locked Loop PLL techniques, the device provides four low skew outputs at speeds up to 133 MHz at V. The outputs can be generated from the PLL for zero delay , or directly from the input for testing , and can be set to tri-state mode or to stop at a low level. The PLL feedback is on-chip and is obtained from the CLKOUT pad. The ICS2305 is available in two different versions. The ICS2305-1 is the base part. The ICS2305-1H is a high drive version with faster rise and fall times. • Clock outputs from 10 to 133 MHz • Zero input-output delay • Four low skew <250 ps outputs • Device-to-device skew <700 ps • Full CMOS outputs with 25 mA output drive capability at TTL levels • 5 V tolerant CLKIN • Tri-state mode for board-level testing • Advanced, low power, sub-micron CMOS process • Operating voltage of V • Industrial temperature range available • Packaged in 8-pin SOIC • Available in Pb lead free package Block Diagram NOTE EOL for non-green parts to occur on 5/13/10 per PDN U-09-01 CLKIN CLKOUT CLK1 CLK2 CLK3 CLK4 IDT / ICS VOLT ZERO DELAY LOW SKEW BUFFER ICS2305 ICS2305 VOLT ZERO DELAY LOW SKEW BUFFER Pin Assignment CLKIN 1 CLK2 2 CLK1 3 GND 4 CLKOUT CLK4 CLK3 8 pin 150mil SOIC ZERO DELAY BUFFER Pin Descriptions Pin Number 1 2 3 4 5 6 7 8 Pin Name CLKIN CLK2 CLK1 GND CLK3 VDD CLK4 CLKOUT Pin Type Pin Description Input Output Power Output Power Output Clock input 5 V tolerant .
