SY88903ALKG-TR

Special Purpose Amplifiers Overview

The SY88903ALKG-TR is a single-channel, burst-mode limiting post amplifier manufactured by Microchip Technology. It operates on a 3.3V supply and supports data rates up to 1.25Gbps. The device features high sensitivity and outputs PECL-level waveforms. It includes a TTL Loss-of-Signal (LOS) indicator. The component is housed in a 10-pin MSOP package with an industrial temperature range.

Special Purpose Amplifiers Feature Summary

• Burst mode operation optimized for passive optical network receivers
• High-sensitivity limiting post amplifier design
• TTL signal loss detection capability

Special Purpose Amplifiers Applications

• Fiber-optic receivers
• Passive optical networks (PON)
• ATM/SONET/SDH support circuits

Special Purpose Amplifiers Procurement Notes

Verify the specific suffix 'ALKG' against official datasheets to confirm pinout and electrical characteristics. Ensure the 10-MSOP package matches the target PCB footprint. Confirm RoHS compliance status prior to integration. Validate that the burst mode functionality aligns with the system's PON requirements.

Special Purpose Amplifiers Selection Notes

Select this component when designing fiber-optic receivers requiring burst-mode processing. It is suitable for applications needing high sensitivity at 1.25Gbps. The PECL output interface must be compatible with downstream logic. Consider the TTL LOS feature for link monitoring needs.
