SY88803VKC-TR

Overview

The SY88803VKC-TR is a low-power limiting post amplifier designed for fiber-optic receivers. It operates from a single +3.3V or +5V power supply and supports data rates up to 155Mbps. The device accepts differential inputs as small as 5mVp-p and outputs PECL level waveforms. It features a TTL Loss-of-Signal (LOS) output with programmable sensitivity via the LOSLVL pin. The component is housed in a 10-pin MSOP package.

Feature Summary

• Quantizes noisy linear signals from transimpedance amplifiers into clean PECL level waveforms
• Generates a chatter-free TTL Loss-of-Signal output with adjustable detection thresholds
• Provides high-sensitivity input amplification for very small signal amplitudes
• Includes an enable input to deassert the true data output without removing the input signal

Applications

• 155Mbps SONET/SDH systems
• Small form factor transceivers
• High-gain line driver and line receiver circuits

Procurement Notes

Verify that the specific suffix 'VKC' corresponds to the commercial temperature range and Sn-Pb lead finish as documented in the manufacturer's ordering information. Confirm that the tape and reel packaging matches the required manufacturing process. Ensure compatibility with the specified operating voltage ranges of +3.0V to +3.6V or +4.5V to +5.5V before integration.

Selection Notes

Select this component when interfacing with transimpedance amplifiers requiring signal quantization for PECL-compatible downstream devices. Consider the 10-pin MSOP package constraints for board layout. Evaluate the need for programmable LOS sensitivity if signal amplitude stability varies over time. Ensure the design accommodates the required external termination resistors for proper PECL output operation.

Part Context

This part belongs to the SY88803V family of low-power limiting post amplifiers originally developed by Micrel, Inc., which was later acquired by Microchip Technology. The series is engineered specifically for optical networking applications where signal integrity from high-gain amplifiers must be maintained at speeds up to 155Mbps.
