ICS527-04

Clock Slicer User Configurable PECL input Zero Delay Buffer

Description

Features

The ICS527-04 Clock Slicer is the most flexible way to

generate an output clock from an input clock with zero

skew. The user can easily configure the device to

produce nearly any output clock that is multiplied or

divided from the input clock. The part supports

non-integer multiplications and divisions. Using

Phase-Locked Loop (PLL) techniques, the device

accepts an input clock up to 200 MHz and produces an

output clock up to 160 MHz.

• Packaged as 28-pin SSOP (150 mil body)

• Synchronizes fractional clocks rising edges

• CMOS in to PECL out

• PECL in to PECL out

• Pin selectable dividers

• Zero input to output skew

• User determines the output frequency - no software

needed

• Slices frequency or period

The ICS527-04 aligns rising edges on PECLIN with

FBPECL at a ratio determined by the reference and

feedback dividers.

• Input clock frequency of 1.5 MHz - 200 MHz

• Output clock frequencies up to 160 MHz

• Very low jitter

• Duty cycle of 45/55

• Operating voltage of 3.3 V

For other PECL output clocks, see the ICS507-01,

ICS525-03, or the MK3707. For PECL in and CMOS

out, see the ICS527-02. For CMOS in and PECL out

with zero delay, use the ICS527-03.

• Advanced, low power CMOS process
