SY88343HL

3.3V, 3.2Gbps CML Limiting Post Amplifier

with High-Gain TTL Loss-of-Signal

General Description

Features

The SY88343HL low-power, high-sensitivity, 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 SY88343HL quantizes these

signals and outputs CML level waveforms.

• High input sensitivity: 4mV_PP

• Single 3.3V power supply

• 155Mbps to 3.2Gbps operation

• Ideal for multi-rate applications

• Low-noise CML data outputs

• High-sensitivity Loss-of-signal (LOS) detection

The SY88343HL operates from a single +3.3V power

supply, over temperatures ranging from –40^oC to +85^oC.

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

rates up to 3.2Gbps and as small as 4mV_PP, it can be

amplified to drive devices with CML/PECL inputs

• Chatter-free open-collector TTL Loss-of-Signal (LOS)

output with internal 4.75kΩ pull-up resistor

• TTL /EN input

• Programmable LOS level set (LOS_LVL

)

• Available in a tiny (3mm x 3mm) 16-pin QFN

The SY88343HL 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_LVL) sets

the sensitivity of the input amplitude detection. LOS

asserts high if the input amplitude falls below the

threshold set by LOS_LVLand de-asserts low otherwise.

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

package

Applications

• APON, BPON, EPON, GEPON, and GPON

• SFP/SFF/GBIC optical transceivers

• Gigabit Ethernet

• 1X and 2X Fibre Channel

• SONET/SDH: OC 3/12/24/48 – STM ¼/8/16

• Line driver and line receiver

output stability under

loss-of-signal condition.

Typically, 3.5dB LOS hysteresis is provided to prevent

chattering.
