SY88803VKI

Overview

The SY88803VKI is a low-power limiting post amplifier manufactured by Microchip Technology. It operates on a single supply voltage of 3.3V or 5V and supports data rates up to 155Mbps. The device features PECL outputs and includes a TTL Loss of Signal (LOS) indicator. It is housed in a 10-pin MSOP package.

Feature Summary

• Provides gain for signals from transimpedance amplifiers
• Quantizes noisy linear signal outputs into clean waveforms
• Outputs PECL level signals compatible with high-speed interfaces
• Includes TTL LOS functionality for fault detection

Applications

• Fiber optic receivers
• Optical network equipment
• Systems connecting to typical transimpedance amplifiers

Procurement Notes

Verify the specific suffix 'VKI' against official Microchip documentation to confirm pinout and electrical characteristics, as variations exist within the SY88803 family. Ensure compatibility with the required 3.3V or 5V supply rails and PECL interface standards before integration.

Selection Notes

Select this component when designing fiber optic receiver stages requiring signal quantization from TIA outputs. It is suitable for applications needing PECL output levels and loss-of-signal detection at speeds up to 155Mbps. Consider power consumption and package size constraints relative to the MSOP-10 form factor.

Part Context

This part belongs to the SY88803 series of limiting post amplifiers designed for optical communications. It addresses the need to condition noisy analog signals from photodiodes and TIAs into digital-compatible formats for downstream processing in optical networking infrastructure.
