DATASHEET ICS570-01 MULTIPLIER AND ZERO DELAY BUFFER Description Features The ICS570-01 is a high-performance Zero Delay Buffer (ZDB) which integrates IDT’s proprietary mixed signal Phased Lock Loop (PLL) techniques. The zero delay feature means that the rising edge of the input clock aligns with the rising edges of the output clock, giving the appearance of no delay through the device. The device includes an on-chip ROM table with nine different mulitplication factors, allowing it to generate many common output frequencies from a single input. • • • • • • • • • • 8-pin MSOP package (3.00 mm x 3.00 mm body) Available in Pb (lead) free package Low input to output skew of 300 ps max Can recover degraded input clock duty cycle Output clock duty cycle of 45/55 Power Down and Tri-State Mode Accepts spread spectrum clock inputs Advanced, low power CMOS process 3.3 V operation Industrial temperature version available Block Diagram Power S1:0 2 ICLK PLL CLK FBIN GND IDT™ / ICS™ MULTIPLIER AND ZERO DELAY BUFFER 1 ICS570-01 REV B 072706 ICS570-01 MULTIPLIER AND ZERO DELAY BUFFER ZDB AND MULTIPLIER Pin Assignment ICLK 1 8 S1 S0 2 7 VDD GND 3 6 VDD FBIN 4 5 CLKOUT Pin Descriptions Pin Number 1 2 3 4 5 6 7 8 Pin Name ICLK S0 GND FBIN CLKOUT VDD VDD S1 Pin Type Input Input Power Input Output Power Power Input Pin Description Clock input.

IDT™ / ICS™ MULTIPLIER AND ZERO DELAY BUFFER 2 ICS570-01 REV B 072706 ICS570-01 MULTIPLIER AND ZERO DELAY BUFFER ZDB AND MULTIPLIER External Components The ICS570-01 requires a minimum number of external components for proper operation. Decoupling capacitors of 0.01 µF should be connected between VDD and GND (pins 3, 6, and 7), as close to the device as possible. A series termination resistor of 33Ω may be used on each clock output pin to reduce reflections. Absolute Maximum Ratings Stresses above the ratings listed below can cause permanent damage to the ICS570-01. These ratings, which are standard values for IDT commercially rated parts, are stress ratings only. Functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over the recommended operating temperature range.
