3.3V/5V 622Mbps PECL LOW-POWER

LIMITING POST AMPLIFIER W/PECL

SIGNAL DETECT

SY88713V

Micrel, Inc.

DESCRIPTION

FEATURES

■ Single 3.3V or 5V power supply

■ Up to 622Mbps operation

The SY88713V low-power limiting post amplifier is

designed for use in fiber optic receivers. The device connects

to typical transimpedance amplifiers (TIAs). The linear signal

output from TIAs can contain significant amounts of noise

and may vary in amplitude over time. The SY88713V

quantizes these signals and outputs PECL level waveforms.

■ Low noise PECL data outputs

■ Chatter-free PECL Signal Detect (SD) output

■ TTL /EN input

■ Programmable SD level set (SD

)

The SY88713V operates from a single +3.3V or +5V

power supply, over temperatures ranging from –40°C to

+85°C. With its wide bandwidth and high gain, signals with

data rates up to 622Mbps and as small as 5mVp-p can be

amplified to drive devices with PECL inputs.

LVL

■ Available in a tiny 10-pin MSOP (3mm) package

The SY88713V generates a PECL SD output. A

programmable signal-detect level set pin (SD ) sets the

LVL

sensitivity of the input amplitude detection. SD asserts high

APPLICATIONS

if the input amplitude rises above the threshold set by SD

LVL

and deasserts low otherwise. /EN deasserts the true output

signal without removing the input signal. Typically 4.6dB

SD hysteresis is provided to prevent chattering.

■ 622Mbps SONET/SDH

■ Small form factor transceivers

■ High-gain line driver and line receiver
