General Description
The SY88149HAL is a high-sensitivity, burst-mode
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.
The SY88149HAL generates a high-gain LVTTL LOS or
SD output. A programmable LOS/SD level set pin
(LOS/SDLVL) 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.
The SY88149HAL operates from a single +3.3V power
supply, over temperatures ranging from –40
oC to +85oC.
With its wide bandwidth and high gain, signals up to
1.25Gbps and as small as 5mVpp can be amplified to
LVPECL levels.
All support documentation can be found on Micrel’s web
site at: www.micrel.com.
