SY58626LMH

Overview

The SY58626LMH 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 drives serial data from DC through 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 throughput with variable CML output swing (200mVPP to 3.0VPP)
• Programmable pre-emphasis: 4 magnitude levels (10% to 33%) and 4 duration settings (60ps to 400ps)
• Unique 3-pin input termination architecture supporting AC- or DC-coupled signals as small as 100mVPK
• Integrated loopback capability with internal input isolation

Applications

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

Procurement Notes

Verify package configuration upon ordering. The SY58626LMH is supplied in a tube containing 32-pin QFN devices. Confirm lead finish specifications match design requirements, as NiPdAu Pb-Free variants are available in both tube and tape-and-reel formats.

Selection Notes

Select this component when interfacing with AC- or DC-coupled differential signals without external termination networks. Ensure VTTIN and VTTOUT pins are utilized for DC-offset control if required by the specific logic family interface. Verify that the 3.3V supply voltage aligns with system power rails.

Part Context

This part belongs to Micrel’s Precision Edge product line, now under Microchip Technology. It is specifically designed to operate in conjunction with the SY58627L receiver buffer, which provides complementary equalization capabilities for complete backplane signal integrity solutions.

Replacement Considerations

The SY58626LMHTR is the identical functional device packaged in tape-and-reel format instead of a tube.
