SY88149HL

3.3V 1.25Gbps Burst-Mode Limiting

Amplifier with Ultra-Fast Signal Assert

Timing

General Description

Features

The SY88149HL is a high-sensitivity, burst-mode capable

limiting post amplifier designed for Optical Line Terminal

(OLT) receiver applications. The SY88149HL 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. For increased

flexibility, this device also includes an option to select

between LOS or SD output. The device can be connected

to burst-mode capable transimpedance amplifiers (TIAs)

using AC or DC coupling.

• Single 3.3V power supply

• <5ns SD assert (LOS de-assert) time

• Option to AUTORESET or Manual RESET LOS output

to HIGH and SD output to LOW

• Option to select LOS or SD output

• Up to 1.25Gbps operation

• Low-noise differential LVPECL data outputs

• 4mVpp input sensitivity

• High sensitivity LOS/SD detect

• Ultra fast LVTTL LOS/SD output

• Squelching function to disable output

The SY88149HL generates a high-gain LOS or SD LVTTL

output. A programmable LOS/SD level pin (LOS/SD_LVL

)

sets the sensitivity of the input amplitude detection. This

device also offers the option to choose between a Loss-of-

Signal (LOS) and a Signal-Detect (SD) output from the

LOS/SD pin based the LOS/SDSEL pin setting. To select

SD output, leave LOS/SDSEL pin open or connect to Vcc;

to select LOS output, tie LOS/SDSEL-to-ground. If the

input signal amplitude falls below the threshold set by

LOS/SD_LVL, LOS will assert high (or SD will de-assert low).

Once the input signal rises above the threshold set by

LOS/SD_LVL, LOS will de-assert low (or SD output will

assert high). The SY88149HL also features a JAM function

which, when active, disables the LVPECL outputs. JAM is

active LOW when SD is selected and active HIGH when

LOS is selected. The LOS/SD output should be fed back to

the JAM input to maintain output stability under an invalid

signal condition. Typically, 3dB SD hysteresis is provided

to prevent chattering.

• Programmable LOS/SD level set (LOS/SD_LVL

)

• Available in a 16-pin (3mmx 3mm) MLF^®package

Applications

• GE-PON/GPON/EPON OLT

• Gigabit Ethernet

• Fibre Channel

• OC-3/12/24 SONET/SDH

• High-gain line driver and line receiver

• Low-gain TIA interface

Markets

• FTTH/FTTP

• Datacom/Telecom

• Optical transceiver

The SY88149HL 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 4mVpp can be amplified to

drive devices with LVPECL inputs.
