3.3V/5V 622Mbps PECL LOW-POWER

LIMITING POST AMPLIFIER W/TTL LOS

DESCRIPTION

FEATURES

■ Single 3.3V or 5V power supply

■ Up to 622Mbps operation

The SY88703V 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 SY88703V

quantizes these signals and outputs PECL level waveforms.

■ Low noise PECL data outputs

■ Chatter-free TTL Loss-of-Signal (LOS) output

■ TTL /EN input

■ Programmable LOS level set (LOS

)

The SY88703V 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 SY88703V generates a TTL LOS output. A

programmable loss-of-signal level set pin (LOS ) sets the

LVL

sensitivity of the input amplitude detection. LOS asserts

high if the input amplitude falls below the threshold set by

APPLICATIONS

LOS

and deasserts low otherwise. /EN deasserts the

LVL

■ 622Mbps SONET/SDH

true output signal without removing the input signal. Typically

4.6dB loss-of-signal hysteresis is provided to prevent

chattering.

■ Small form factor transceivers

■ High-gain line driver and line receiver
