General Description
The SY88309BL low-power limiting post amplifiers are
designed for use in fiber-optic receivers. These devices
connect 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 SY88309BL quantizes these signals and output
PECL-level waveforms.
The SY88309BL operates from a single +3.3V power
supply, over temperatures ranging from –40
oC to +85oC.
With their wide bandwidth and high gain, signals with
data rates up to 3.2Gbps, and as small as 10mVpp, can
be amplified to drive devices with CML or PECL inputs.
It generates a Signal Detect (SD) open-collector TTL
output. The SD function is optimized to detect a larger
and wider input range, as shown in the characteristic
curve on page 6. A programmable signal-detect level set
pin (SDLVL) sets the sensitivity of the input amplitude
detection.
SD asserts high if the input amplitude rises above the
threshold sets by SDLVL and de-asserts low otherwise.
The SD output can be fed back to the EN input to
maintain stability. Typically, 3.5dB LOS/SD hysteresis is
provided to prevent chattering.
Datasheet and support documentation can be found on
Micrel’s web site at: www.micrel.com.
