SY58626LMH-TR

Overview

The SY58626LMH-TR is a high-speed, low-jitter transmit buffer optimized for backplane and transmission line data-path management in Automatic Test Equipment (ATE) and Test & Measurement systems. It supports serial data rates from DC to 6.4Gbps with a programmable differential output swing ranging from 200mVPP to 3.0VPP. The device features selectable pre-emphasis magnitude and duration to extend transmission range. It operates on a single 3.3V ±10% supply within the commercial temperature range of 0°C to +70°C.

Feature Summary

DC-to-6.4Gbps data rate throughput with integrated loopback capability
Programmable output swing control from 200mVPP to 3.0VPP via TXVCTRL pin
Selectable pre-emphasis magnitude (10% to 33%) and duration (60ps to 400ps)
Unique 3-pin input termination architecture supporting AC- or DC-coupled signals

Applications

ATE and T&M backplane management
Combination FR4, cable, and interconnect driver applications
Cable drivers requiring DC-offset control

Procurement Notes

Verify that the ordering suffix 'TR' corresponds to the Tape & Reel packaging format as specified in the datasheet. Confirm the component grade matches the Commercial operating range (0°C to +70°C). Ensure the package marking includes the bar-line Pb-Free indicator and NiPdAu lead finish.

Selection Notes

Select this component when interfacing with the SY58627L receiver for backplane applications. Use the variable resistor method between VREF-CTRL and VCC to drive TXVCTRL if analog swing adjustment is required. For fixed CML swing applications, connect TXVCTRL directly to VREF-FIXED to achieve an 800mVPP output.

Part Context

This part belongs to Micrel’s Precision Edge product line, now under Microchip Technology. It is specifically designed to work in conjunction with the SY58627L receive buffer. The LMH variant denotes the 32-pin QFN package with Lead-Free and NiPdAu finish specifications.
