ICS388

Quad PLL Quick Turn Clock Synthesizer

Description

Features

• Packaged as 20 pin SSOP (QSOP)

• Quick turn frequency programming allows

samples as quickly as one day

The ICS388 QTClock™ generates up to 9 high quality,

high frequency clock outputs including a reference

from a low frequency crystal or clock input. It is designed

to replace crystals and crystal oscillators in most

electronic systems. The ICS388 contains a One Time

Programmable (OTP) ROM which is factory programmed

with PLL divider values to output a broad range of

frequencies up to 200 MHz, allowing customer

requests for different frequencies to be shipped in 1-3

days. Programming features include a selectable

frequency table and up to 4 low-skew outputs.

• Up to 4 outputs can be low-skew

• Can include 8 selectable output frequencies

• Up to 5 reference outputs

• Replaces multiple crystals and oscillators

• Output frequencies up to 200 MHz at 3.3V

• Input crystal frequency of 5 - 27 MHz

• Input clock frequency of 2 - 50 MHz

• Duty cycle of 45/55

Using Phase-Locked-Loop (PLL) techniques, the

device runs from a standard fundamental mode,

inexpensive crystal, or clock. It can replace multiple

crystals and oscillators, saving board space and cost.

• Operating voltages of 3.3 V or 5 V

• Advanced, low power CMOS process
