The SY75572L is a high-speed, fully differential 1:2 clock fanout buffer with a 2:1 input MUX optimized to provide two identical output copies with 137fs phase jitter and a maximum of 50ps output-to-output skew. Designed to be used with PCI Express applications, the SY75572L accepts and outputs HCSL or LVDS logic levels.The SY75572L 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 16-pin QFN lead-free package.The SY75572L is part of Micrel’s high-speed, ultra-low jitter, PrecisionEdge™ product line. The SY75572L supports PCIe Gen1-Gen3 requirements with sufficient performance margin for pending PCIe Gen4 applications.
Additional Features
Two differential pairs of LVDS or HCSL outputs
Two pairs of differential inputs accept LVDS or HCSL logic levels
267MHz maximum frequency
Ultra-low phase jitter:
137fsRMS, 200MHz (12kHz–20MHz)
153fsRMS, 156.25MHz (12kHz–20MHz)
212fsRMS, 100MHz (12kHz–20MHz)
<2ps total jitter (peak-to-peak), 200MHz (BER = 10-12)
50ps output-to-output skew
3.3V ±5% power supply operation
-40°C to +85°C operating temperature
Available in 16-pin (3mm × 3mm) QFN lead-free package
