Description
The AK8181E is a member of AKM’s LVPECL clock fanout buffer family designed for telecom, networking and computer applications, requiring a range of clocks with high performance and low skew.
Features
- Four differential 3.3V LVPECL outputs Selectable crystal or differential clock inputs Clock output frequency up to 650MHz Translates any single-ended input signal to 3.3V LVPECL levels with resistor bias on PCLKn input Output skew : 10ps (typical) Part-to-part skew : 150ps (maximum) Propagation delay : 0.9ns (typical) Additive phase jitter(RMS): PCLKp/n@156.25MHz : 0.04ps (typical) XTAL@50MHz : 0.14ps (typical) Operating Temperature Range: -40 to +85℃ Package: 20-pin TSSOP (Pb free) Pin compatib.
