SY898531L

Precision Differential 3.3V Low Skew

LVPECL 1:9 Fanout Buffer

General Description

The SY898531L is a 3.3V, low skew, 1:9 LVPECL fanout

buffer with two selectable clock input pairs. Most standard

differential input levels can be applied to the CLK, /CLK

pair while LVPECL, CML, or SSTL input levels can be

applied to the PCLK, /PCLK pair. To eliminate runt pulses

on the outputs during asynchronous assertion/de-assertion

of the clock enable pin, the clock enable is synchronized

with the input signal.

Precision Edge^®

Features

∑ Provides nine differential 3.3V LVPECL copies

∑ Selects between differential CLK, /CLK or LVPECL clock

inputs

∑ CLK, /CLK pair accepts LVDS, LVPECL, LVHSTL,

SSTL, HCSL input levels

The SY898531L operates from a 3.3V ±5% supply and is

guaranteed over the full industrial temperature range of

0°C to +70°C. The SY898531L is part of Micrel’s high-

speed, Precision Edge^®product line.

∑ PCLK, /PCLK pair accepts LVPECL, CML, SSTL input

levels

∑ Guaranteed AC performance over temperature and

supply voltage:
