SY88053ALMG TR

Special Purpose Amplifiers Overview

The SY88053ALMG TR is a limiting post amplifier designed for fiber-optic receivers operating up to 12.5Gbps. It features a programmable decision threshold for BER optimization in noisy WDM environments with EDFAs or Raman amplifiers. The device connects to typical transimpedance amplifiers (TIAs) and operates from a single +3.3V supply over temperatures of –40°C to +85°C. It detects signals as low as 15mVpp, generates a Loss-of-Signal open-collector TTL output, and includes an enable input. The component is housed in a 16-pin MLF package.

Special Purpose Amplifiers Feature Summary

• Programmable decision threshold control adjusts signal crossing points to optimize Bit Error Rate in noisy applications
• Generates a Loss-of-Signal open-collector TTL output with programmable sensitivity via external resistor
• Features differential CML data outputs with internal termination for driving transmission lines
• Includes an enable input that de-asserts the true output signal without removing the input signal

Special Purpose Amplifiers Applications

• WDM Systems
• 10xGigabit Ethernet
• 8xFibre Channel
• SONET/SDH: OC192 – STM64
• Low-gain TIA interface

Special Purpose Amplifiers Procurement Notes

Verify the specific ordering suffix 'TR' corresponds to the tape and reel packaging format required for automated assembly processes. Confirm the component status against current manufacturer records, as legacy documentation may indicate end-of-life status. Ensure compatibility with the 16-pin MLF footprint during PCB layout verification.

Special Purpose Amplifiers Selection Notes

Select this component when designing fiber-optic receivers requiring high sensitivity for signals down to 15mVpp. It is suitable for systems utilizing optical amplifiers where noise distribution is uneven. Consider the programmable threshold feature if optimizing BER performance in WDM environments is critical. Verify power supply constraints align with the single +3.3V requirement.
