SY58626L Datasheet | Micrel Semiconductor

DC-to-6.4Gbps Backplane Transmit Buffer with Selectable Output Pre-emphasis, I/O DC-Offset Control, and 200m V-3.0VPP Output Swing General Description The SY58626L high-speed, low jitter transmit buffer is optimized for backplane and transmission line data-path management applications in Automatic Test Equipment (ATE) and Test & Measurement (T&M) systems. The buffer includes a CML patible, variable swing output with selectable pre-emphasis. The SY58626L is capable of driving serial data from DC through 6.4Gbps with a 3VPP (1.5VPK single ended) differential swing. The SY58626L differential input includes Micrel’s unique, 3-pin input termination architecture that directly interfaces to any DC- or AC-coupled, differential signal as small as 100m VPK without any termination resistor networks in the signal path. The outputs are 50Ω source-terminated CML with a programmable output swing from 200m VPP to 3VPP (100m VPK to 1.5VPK). The SY58626L includes an output stage that provides 4 levels of pre-emphasis. The output pre-emphasis level is programmed with a three-bit interface. Unlike other transmitter solutions, the output pre-emphasis duration can be programmed from 60ps to 400ps. The SY58626L operates at 3.3V ±10% supply and is guaranteed over the mercial temperature range of 0°C to +70°C. The SY58626L transmitter is optimized to work with the SY58627L receiver. The SY58626L is part of Micrel’s high-speed, Precision Edge® product line. Data sheets and support documentation can be found on Micrel’s website at: .micrel..
