HMC841LC4B

HMC841LC4B v02.0910 43 Gbps, D-TYPE FLIP-FLOP w/ PROGRAMMABLE OUTPUT VOLTAGE Features Supports Data Rates up to 43 Gbps Low Power Consumption: 630 mW Fast Rise and Fall Times: 12/12 ps Single Ended or Differential Operation Adjustable Differential Output Voltage Swing: 200 - 850 mVp-p 24 Lead 4x4mm SMT Package: 16mm2 Typical Applications The HMC841LC4B is ideal for: • OC-768 and SDH STM-256 Equipment 7 HIGH SPEED LOGIC - SMT • RF ATE Applications • Serial Data Transmission up to 43 Gbps • Digital Logic Systems up to 43 Gbps • Broadband Test & Measurement Functional Diagram General Description The HMC841LC4B is a D-type Flip Flop designed to support data transmission rates of up to 43 Gbps, and clock frequencies as high as 43 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. The HMC841LC4B also features an output level control pin, VAC, which allows for loss compensation or for signal level optimization. All input signals to the HMC841LC4B are terminated with 50 Ohms to ground on-chip, and maybe either AC or DC coupled. The differential outputs of the HMC841LC4B may be either AC or DC coupled. Outputs can be connected directly to a 50 Ohms-to-ground terminated system, while DC blocking capacitors should be used if the terminating system is 50 Ohms to a non-ground DC voltage. The HMC841LC4B operates from a single -3.3V DC supply and is available in a ceramic RoHS compliant 4x4 mm SMT package.
