HMC841LC4B v02.0910 HIGH SPEED LOGIC - SMT 7 43 Gbps, D-TYPE FLIP-FLOP w/ PROGRAMMABLE OUTPUT VOLTAGE Typical Applications Features The HMC841LC4B is ideal for: Supports Data Rates up to 43 Gbps • OC-768 and SDH STM-256 Equipment Low Power Consumption: 630 mW • RF ATE Applications Fast Rise and Fall Times: 12/12 ps • Serial Data Transmission up to 43 Gbps Single Ended or Differential Operation • Digital Logic Systems up to 43 Gbps Adjustable Differential Output Voltage Swing: 200 - 850 mVp-p • Broadband Test & Measurement 24 Lead 4x4mm SMT Package: 16mm2 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. Electrical Specifications, TA = +25°C, Vee = -3.3V Conditions Min. Typ.
