SY75578LMG

SY75578L PCIe Fanout Buffer 267MHz, 8 HCSL Outputs with 2 Input MUX PrecisionEdge™ General Description The SY75578L is a high-speed, fully differential 1:8 clock fanout buffer optimized to provide eight identical output copies with 130fs phase jitter and maximum 100ps outputto-output skew. Designed to be used with PCI-Express applications, SY75578L accepts HCSL/LVDS and outputs HCSL logic levels. The SY75578L operates from a 3.3V ±5% power supply and is guaranteed over the full industrial temperature range (40°C to +85°C). It is available in a 32 pin QFN lead-free package. The SY75578L is part of Micrel’s high-speed, ultra-low jitter, PrecisionEdge™ product line. Datasheets and support documentation are available on Micrel’s web site at: www.micrel.com.
