SY88149HAL

1.25Gbps Burst-Mode Limiting Amplifier

with Ultra-Fast Signal Assert Timing

Features

General Description

• <5ns SD Assert (LOS Deassert) time

The SY88149HAL is

high-sensitivity, burst-mode

• Option to AUTO RESET or manual RESET LOS/SD

capable, limiting-post amplifier designed for FTTH PON

optical line terminal (OLT) receiver applications. The

SY88149HAL satisfies the strict timing restrictions of the

GPON standards by providing ultra-fast loss-of-signal

(LOS) or signal-detect (SD) output. Auto reset and manual

reset options are provided to control LOS/SD output

timing. The device can be connected to burst-mode

capable transimpedance amplifiers (TIAs) using AC or DC

coupling.

output

• Selectable LOS/SD output option

• High-sensitivity LOS/SD signal detect

• Low-noise LVPECL data outputs

• Squelching function to maintain output stability

• Programmable LOS/SD level set (LOS/SD_LVL

)

• 5mVpp input sensitivity

The SY88149HAL generates a high-gain LVTTL LOS or

SD output. A programmable LOS/SD level set pin

(LOS/SD_LVL) sets the sensitivity of the input amplitude

detection. For increased flexibility, this device also

includes an option to select between LOS or SD output by

using the LOS/SD SEL pin. The LOS/SD output can be fed

back to the JAM input to maintain data output stability

under an invalid input signal conditions. Typically, 3dB

LOS/SD hysteresis is provided to prevent chattering.

• 1.25Gbps operation

• Single 3.3V power supply

• Available in a 16-pin (3mm × 3mm) QFN^®package

Applications

• GE-PON/GPON

• Gigabit Ethernet

• Fibre Channel

• OC-3/12/24 SONET/SDH

• High-gain line driver and line receiver

• Low-gain TIA interface

The SY88149HAL operates from a single +3.3V power

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

With its wide bandwidth and high gain, signals up to

1.25Gbps and as small as 5mVpp can be amplified to

LVPECL levels.
