SY75578L PCIe Fanout Buffer 267MHz, 8 HCSL Outputs with 2 Input MUX PrecisionEdge Features General Description Eight differential pairs of HCSL outputs The SY75578L is a high-speed, fully differential 1:8 clock Two pairs of differential inputs accept LVDS or HCSL fanout buffer optimized to provide eight identical output logic levels copies with 130fs phase jitter and maximum 100ps output- to-output skew. Designed to be used with PCI-Express 267MHz max frequency applications, SY75578L accepts HCSL/LVDS and outputs Ultra low phase jitter: HCSL logic levels. 130fs , 200MHz (12kHz20MHz) rms The SY75578L operates from a 3.3V 5% power supply <100ps output-to-output skew and is guaranteed over the full industrial temperature 3.3V 5% power supply operation range ( 40C to +85C). It is available in a 32 pin QFN 40C to +85C Industrial operating temperature lead-free package. Available in 32-pin QFN lead-free package The SY75578L is part of Micrels high-speed, ultra-low jitter, PrecisionEdge product line.
