The HMC853LC3 is a D-Type Flip-Flop designed to support data transmission rates of up to 28 Gbps, and clock frequencies as high as 28 GHz. During normal operation, data is transferred to the outputs on the positive edge of the clock. Reversing the clock inputs allows for negative-edge triggered applications.All differential inputs to the HMC853LC3 are CML and terminated on-chip with 50 Ω to the positive supply, VCC, and may be AC or DC coupled. The differential CML outputs are source terminated to 50 Ω and may also be AC or DC coupled. Outputs can be connected directly to a 50 Ω VCC-terminated system, while DC blocking capacitors may be used if the terminating system is 50 Ω to ground. The HMC853LC3 also features an output level control pin, VR, which allows for loss compensation or signal-level optimization. the HMC853LC3 operates from a single 3.3 V supply and is available in ROHS-compliant 3×3 mm SMT package.APPLICATIONSRF ATE ApplicationsBroadband Test & MeasurementSerial Data Transmission up to 28 GbpsDigital Logic Systems up to 28 GHz
