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

• Translates LVCMOS/LVTTL input signals to LVDS levels

• <40ps output-to-output skew

• <3ns propagation delay

• <400ps rise/fall times

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.

• 3.3V ±5% operating supply

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

• Available in 20-pin TSSOP
