AMPLIFIER WITH TTL LOS

designed for use in fiber optic receivers. The device connects

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 SY88773V

quantizes these signals and outputs typically 800mV

voltage-limited waveforms.

range of –40 C to +85 C. With its wide bandwidth and high

gain, signals with data rates up to 3.2Gbps and as small as

collector TTL output with internal 4.75k

programmable, loss-of-signal level set pin (LOSLVL) sets

the sensitivity of the input amplitude detection. LOS asserts

high if the input amplitude falls below the threshold set by

LOSLVL and de-asserts low otherwise. LOS can be fed

back to the enable (/EN) input to maintain output stability

under a loss-of-signal condition. /EN de-asserts the true

output signal without removing the input signal. Typically

4.6dB LOS hysteresis is provided to prevent chattering.
