HMC848LC5 v01.1010 MUX & DEMUX - SMT 3 45 Gbps, 1:4 DEMUX WITH PROGRAMMABLE OUTPUT VOLTAGE Typical Applications Features The HMC848LC5 is ideal for: Supports Data Rates up to 45 Gbps • SONET OC-768 Half Rate Clock Input • RF ATE Applications Quarter Rate Reference Clock Output • Broadband Test & Measurements Fast Rise and Fall Times: 25 / 21 ps • Serial Data Transmission up to 45 Gbps Programmable Differential Output Voltage Swing: 300 - 1000 mVp-p • High Speed ADC Interfacing Single Supply: +3.3V 32 Lead Ceramic 5x5 mm SMT Package: 25 mm2 Functional Diagram General Description The HMC848LC5 is a 1:4 demultiplexer designed for data deserialization up to 45 Gbps. The device uses both rising and falling edges of the half-rate clock to sample the input data in sequence, D0-D3 and latches the data onto the differential outputs. A quarter-rate clock output generated on-chip can be used to clock the data into other devices. All clock and data inputs / outputs of the HMC848LC5 are CML and terminated on-chip with 50 Ohms to the VCC, and may be DC or AC coupled. The inputs and outputs of the HMC848LC5 may be operated either differentially or single-ended. The HMC848LC5 also features an output level control pin, VCTRL, which allows for loss compensation or signal level optimization. The HMC848LC5 operates from a single +3.3V supply and is available in ROHS compliant 5x5 mm SMT package. Electrical Specifications, TA = +25°C, Vcc = 3.3V Conditions Min. Typ.
