4:1 OR 2:1 DIFFERENTIAL-TO-3.3V LVPECL / ECL CLOCK MULTIPLEXER
FEATURES
• High speed differential multiplexer. The device can be configured as either a 4:1 or 2:1 multiplexer • 1 differential 3.3V LVPECL output • 4 selectable CLK, nCLK inputs • CLK, nCLK pair can accept the following differential input levels: LVDS, LVPECL, LVHSTL, SSTL, HCSL • Maximum output frequency up to 750MHz • Translates any single ended input signal to 3.3V LVPECL levels with resistor bias on nCLKx input • Part-to-part skew: 150ps (maximum) • Propagation delay: 1.5ns (maximum) • LVPECL mode operating voltage supply range: VCC = 3.135V to 3.465V, VEE = 0V • ECL mode operating voltage supply range: VCC = 0V, VEE = -3.135V to -3.
