SY89645L

Precision Low Skew, 1-to-4 LVCMOS/LVTTL-

to-LVDS Fanout Buffer

General Description

The SY89645L is a 3.3V, fully differential, low skew, 1:4

LVDS fanout buffer that accepts LVTTL or LVCMOS

inputs. It is capable of processing clock signals as fast

as 650MHz. The LVDS signals are optimized to provide

less than 40ps of output skew.

Precision Edge^®

Features

The single-ended input takes a 3.3V LVTTL or

LVCMOS, with a signal swing as small as 1.2V. The

outputs are 280mV LVDS, with fast rise and fall times,

guaranteed to be less than 400ps.

• Four identical LVDS outputs

• CLKIN accepts LVCMOS or LVTTL input levels

• Maximum output frequency: 650MHz

The SY89645L operates from a 3.3V + 5% power

supply and is guaranteed over the full industrial

temperature range (–40°C to +85°C). The SY89645L is

part of Micrel’s Precision Edge^®product line. Data

sheets and support documentation can be found on

Micrel’s web site at: www.micrel.com.

• Translates LVCMOS/LVTTL input signals to LVDS

levels

• <40ps output-to-output skew

• <3ns propagation delay

• <400ps rise/fall times

• 3.3V ±5% operating supply

• Industrial temperature range: –40°C to +85°C

• Available in 20-pin TSSOP
