SERIAL PROGRAMMABLE QUAD PLL VERSACLOCK SYNTHESIZER

ICS308

Description

Features

The ICS308 is a versatile serially programmable, quad

PLL clock source. The ICS308 can generate any

frequency from 250 kHz to 200 MHz, and up to 6

different output frequencies simultaneously. The

outputs can be reprogrammed on the fly, and will lock to

a new frequency in 10 ms or less. Smooth transitions

(in which the clock duty cycle remains roughly 50%) are

guaranteed if the output divider is not changed.

• Packaged in 20-pin SSOP (QSOP)

• Available in Pb (lead) free package

• Operating voltage of 3.3 V

• Highly accurate frequency generation

•M/N Multiplier PLL: M = 1..2048, N = 1..1024

• Serially programmable: user determines the output

frequency via a 3-wire interface

The device includes a PDTS pin which tri-states the

output clocks and powers down the entire chip.

• Eliminates need for custom quartz oscillators

• Input crystal frequency of 5 - 27 MHz

•Optional programmable on-chip crystal capacitors

• Output clock frequencies up to 200 MHz

• Reference clock output

The ICS308 default for non-programmed start-up are

buffered reference clock outputs on all clock output

pins.

• Power down tri-state mode

• Very low jitter
