Description
The ICS670-04 is a high speed, low phase noise, Zero Delay Buffer (ZDB) which integrates ICS’ proprietary analog/digital Phase Locked Loop (PLL) techniques. It is identical to the ICS670-02, but with an increased maximum output frequency of 210 MHz. Part of ICS’ ClockBlocksTM family, the part’s zero delay feature means that the rising edge of the input clock aligns with the rising edges of the outputs giving the appearance of no delay through the device. There are two identical outputs on the chip. The FBCLK should be used to connect to the FBIN. Each output has its own output enable pin.
