HMC856LC5

HMC856 is a wideband time delay device with a 5bit digital control designed for timing compensation or clock skew management applications. The time delay provides nearly 100ps (maximum) of delay range with 3ps resolution and supports 28Gbps data. The monotonic delay is compensated for stable operation over both power supply and temperature variation. All differential inputs to the device are current mode logic (CML) and terminated on chip with 50 ohm to the positive supply ground, GND, and can be ac or dc-coupled. The differential CML outputs are source terminated to 50 ohm and can also be ac or dc coupled. Connect outputs directly to a 50 ohm ground terminated system or drive devices with CML logic input. It is used in applications such as SONET OC-192, high speed serial logic, clock and data recovery, broadband test and measurement equipment, frequency synthesis, matched timing etc.
