General Description

The SY88289HL low-power, high-sensitivity, limiting

post amplifier is designed for use in fiber-optic receivers.

The

amplifiers (TIAs). The linear signal output from TIAs can

contain significant amounts of noise and may vary in

amplitude over time. The SY88289HL quantizes these

signals and outputs CML-level waveforms.

The SY88289HL operates from a single +3.3V power

supply, over temperatures ranging from –40

With its wide bandwidth, high gain, and signals with data

rates up to 3.2Gbps and as small as 4mV

amplified to drive devices with CML/PECL inputs.

The SY88289HL generates a high-gain loss-of-signal

(LOS) open-collector TTL output. This function has a

high-gain input stage for increased LOS sensitivity. A

programmable loss-of-signal level-set pin (LOS

the sensitivity of the input amplitude detection. LOS

asserts high if the input amplitude falls below the

threshold sets by LOS

The enable bar input (/EN) de-asserts the true output

signal without removing the input signal. The LOS

output can be fed back to the /EN input to maintain

output

Typically, 3.5dB LOS hysteresis is provided to prevent

chattering.
