General Description

The AV9170 generates an output clock which is synchronized to a given continuous input clock with zero delay (±1ns at 5V VDD). Using ICS’s proprietary phaselocked loop (PLL) ana-log CMOS technology, the AV9170 is useful for regenerating clocks in high speed systems where skew is a major concern. By the use of the two select pins, multiples or divisions of the input clock can be generated with zero delay (see Tables 2 and 3). The standard versions produce two outputs, where CLK2 is always a divide by two version of CLK1.
