SY75572L 267MHz 1:2 3.3V HCSL/LVDS Fanout Buffer PrecisionEdge General Description Features The SY75572L is a high-speed, fully differential 1:2 clock Two differential pairs of LVDS or HCSL outputs fanout buffer with a 2:1 input MUX optimized to provide Two pairs of differential inputs accept LVDS or HCSL two identical output copies with 137fs phase jitter and a logic levels maximum of 50ps output-to-output skew. Designed to be 267MHz maximum frequency used with PCI Express applications, the SY75572L Ultra-low phase jitter: accepts and outputs HCSL or LVDS logic levels. 137fs , 200MHz (12kHz20MHz) RMS The SY75572L operates from a 3.3V 5% power supply 153fs , 156.25MHz (12kHz20MHz) RMS and is guaranteed over the full industrial temperature 212fs , 100MHz (12kHz20MHz) range ( 40C to +85C). It is available in a 16-pin QFN RMS 12 lead-free package. <2ps total jitter (peak-to-peak), 200MHz (BER = 10 ) 50ps output-to-output skew The SY75572L is part of Micrels high-speed, ultra-low jitter, PrecisionEdge product line. The SY75572L 3.3V 5% power supply operation supports PCIe Gen1-Gen3 requirements with sufficient 40C to +85C operating temperature performance margin for pending PCIe Gen4 applications. Available in 16-pin (3mm 3mm) QFN lead-free Datasheets and support documentation are available on package Micrels website at: www.micrel.com.
