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/SDLVL  
)
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/SDLVL, LOS will assert high (or SD will de-assert low).  
Once the input signal rises above the threshold set by  
LOS/SDLVL, 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/SDLVL  
)
• Available in a 16-pin (3mmx 3mm) QFN 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 –40oC to +85oC.  
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.
