SY88063AL

SY88063AL 3.3V, 12.5Gbps Limiting Post Amplifier with Automatic Digital Offset Correction General Description Features The SY88063AL is a multi-rate limiting post amplifier designed for fiber-optic transceivers applications up to 12.5Gbps. It features an automatic digital offset correction function. The offset correction feature will automatically counteract any inherent offset present in the input signal and amplifier. The highly sensitive SY88063AL can amplify input signals as low as 20mVpp at 12.5Gbps or 10mVpp at 10.3Gbps to differential CML output levels. The SY88063AL generates a loss-of-signal (LOS) opencollector TTL output. A 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. The enable input (/EN) de-asserts the true output signal without removing the input signal. The LOS output can be fed back to the /EN input...
