SY88803VKG-TR

Overview

The SY88803VKG-TR is a low-power limiting post amplifier manufactured by Microchip Technology, housed in a 10-pin MSOP package. It operates from a single +3.3V or +5V power supply and supports data rates up to 155Mbps. The device features PECL differential outputs with a typical gain of 38 dB and a 3dB bandwidth of 200 MHz. It includes a TTL Loss-of-Signal (LOS) output with programmable sensitivity via the LOSLVL pin and an /EN input for signal control.

Feature Summary

• Provides high-gain amplification for small input signals as low as 5mVp-p
• Generates a chatter-free TTL Loss-of-Signal output with programmable threshold
• Outputs quantized PECL level waveforms suitable for driving PECL inputs

Applications

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

Procurement Notes

Verify that the specific ordering suffix matches the required industrial temperature range (-40°C to +85°C) and lead finish specifications. Confirm the tape and reel packaging format aligns with automated assembly requirements. Ensure compatibility with the intended power supply voltage levels before finalizing procurement orders.

Selection Notes

Select this component when interfacing with transimpedance amplifiers in fiber-optic receivers requiring signal quantization. Consider the 10-pin MSOP package size for space-constrained designs. Evaluate the need for programmable loss-of-signal detection and TTL enable functionality within the system architecture.

Part Context

This part belongs to the SY88803 family of limiting post amplifiers designed for optical networking applications. It serves as a post-amplifier stage following a transimpedance amplifier to condition noisy linear signals into clean digital waveforms. The device integrates both amplification and signal detection capabilities in a compact surface-mount package.

Replacement Considerations

SY88803VKC is a commercial grade alternative in the same package. SY88803VKG is the tube-packaged version of the industrial grade part.
