The HMC911LC4B is a DC to 24 GHz broadband time delay product that provides a continuously variable delay from 0 ps to 70 ps while maintaining a constant differential output voltage swing. The device accepts either single-ended or differential input data, while the differential output swing is adjustable from 150 mVp-p to 800 mVp-p. The modulation bandwidth is 1.6 GHz, which is the highest phase modulation bandwidth available in the market.
Suitable for both clock and data retiming applications, the HMC911LC4B features internal temperature compensation and bias circuitry to minimize delay variations with temperature. All RF input and outputs of the device are internally terminated with 50 Ohms to Vcc, and may either be AC or DC coupled. Output pins can be connected directly to a 50 Ohm to Vcc terminated system, while DC blocking capacitors must be used if the terminated system input is 50 Ohms to a DC voltage other than Vcc.
The HMC911LC4B is housed in a ceramic RoHS compliant 4 x 4 mm SMT package, and is fully specified for operation from -40 °C to +85 °C.
