SY88903AL Overview
Key Features
- Single 3.3V power supply post amplifier is designed for use in fiber-optic receivers
- 622Mbps to 1.25Gbps operation amplifiers (TIAs). The linear signal output from TIAs can
- Low-noise PECL data outputs contain significant amounts of noise and may vary in
- High gain LOS amplitude over time. The SY88903AL quantizes these signals and outputs PECL level waveforms
- TTL /EN input Signals with data rates from 622Mbps up to 1.25Gbps
- Programmable LOS level set (LOSLVL) and as small as 5mVpp, can be amplified to drive
- GPON/GEPON/EPON Signal level set pin (LOSLVL) sets the sensitivity of the input amplitude detection. LOS asserts high if the input
- Gigabit Ethernet, 1062Mbps Fibre Channel amplitude falls below the threshold set by LOSLVL and
- OC-12/24 SONET/SDH de-asserts low otherwise. The enable bar input (/EN)
- Low-gain TIA interface de-asserts the true output signal without removing the
