SY75576LKY-TR

Clock Buffers, Drivers Overview

The SY75576LKY-TR is a high-speed, fully differential 1:4 clock fanout buffer from the PrecisionEdge™ series. It accepts HCSL or LVDS logic levels on two pairs of differential inputs and provides four identical output copies in a 20-pin TSSOP package. The device operates from a 3.3V ± 5% power supply (3.135V to 3.465V) over an industrial temperature range of −40°C to +85°C. Key electrical specifications include a maximum HCSL frequency of 267MHz and an LVDS frequency of 100MHz. Propagation delay is guaranteed at a maximum of 2ns, with ultra-low phase jitter ranging from 137fsrms at 200MHz to 212fsrms at 100MHz.

Clock Buffers, Drivers Feature Summary

Clock Buffers, Drivers Procurement Notes

Verify that the ordering suffix '-TR' corresponds to the Tape and Reel packaging format as specified in the datasheet's Ordering Information section. Confirm the component is sourced from authorized channels to ensure authenticity, as the part was originally manufactured by Micrel, Inc., which has since been acquired by Microchip Technology.

Clock Buffers, Drivers Selection Notes

Select this component when low jitter performance is critical for clock distribution networks. Ensure the input signal matches either HCSL or LVDS standards, as the device supports both. Verify that the system power supply remains within the 3.135V to 3.465V operating range and that the PCB layout accommodates the 20-pin TSSOP package dimensions.

Clock Buffers, Drivers Part Context

The SY75576L belongs to Micrel’s PrecisionEdge™ product line, designed for high-speed, ultra-low jitter applications. The 'K' in the part number indicates the TSSOP-20 lead-free package type, while the 'Y' denotes the industrial temperature range (-40°C to +85°C). The '-TR' suffix specifically identifies the tape and reel shipping configuration.
