SY88343BLMG-TR

Special Purpose Amplifiers Overview

The SY88343BLMG-TR is a low-power limiting post amplifier designed for fiber-optic receivers. It operates from a single +3.3V supply and supports data rates up to 3.2 Gbps. The device features high gain with a typical differential voltage gain of 38 dB, capable of amplifying input signals as small as 5 mVPP. It provides CML data outputs and an open-collector TTL Loss-of-Signal (LOS) output. The component is housed in a 16-Lead VQFN package.

Special Purpose Amplifiers Feature Summary

• Generates chatter-free open-collector TTL Loss-of-Signal output with internal pull-up resistor
• Features programmable LOS level set pin for adjustable sensitivity
• Provides low-noise CML data outputs suitable for driving AC-coupled inputs
• Includes TTL enable bar input for output stability control

Special Purpose Amplifiers Applications

• APON, BPON, EPON, and GPON systems
• Gigabit Ethernet interfaces
• Fibre Channel connections
• OC-3 and OC-12/24 SONET/SDH networks

Special Purpose Amplifiers Procurement Notes

Verify the specific ordering suffix '-TR' confirms the tape and reel packaging format, distinct from tube variants. Confirm the 'MG' designation matches the required 16-lead VQFN package dimensions and thermal pad requirements. Ensure the 'L' suffix aligns with the specified 3.3V operating voltage range. Validate that the component meets RoHS compliance standards for the intended application environment.

Special Purpose Amplifiers Selection Notes

Select this component when interfacing with AC-coupled transimpedance amplifiers requiring signal quantization. It is suitable for applications needing high sensitivity to detect signals down to 5 mVPP. Consider the device for designs requiring a programmable loss-of-signal threshold to prevent output chattering. Ensure the system can accommodate the 16-lead VQFN footprint and thermal dissipation needs.
