HMC847LC5 v01.1010 45 Gbps, 4:1 MUX WITH DUTY CYCLE CONTROL & PROGRAMMABLE OUTPUT VOLTAGE MUX & DEMUX - SMT 3 Typical Applications Features The HMC847LC5 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: 11 / 12 ps • Serial Data Transmission up to 45 Gbps Programmable Differential Output Voltage Swing: 250 - 900 mVp-p • High Speed DAC Interfacing Single Supply: +3.3V 32 Lead Ceramic 5x5 mm SMT Package: 25 mm2 Functional Diagram General Description The HMC847LC5 is a 4:1 multiplexer designed for 45Gbps data serialization. The mux latches the four differential inputs on the transition points of the input clock. The device uses both rising and falling edges of the half-rate clock to serialize the data. A quarter-rate clock output, which is synchronous to the data output of HMC847LC5, is generated on chip. All clock and data inputs / outputs of the HMC847LC5 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 HMC847LC5 may be operated either differentially or single-ended. The HMC847LC5 also features an output level control pin, VCTRL, which allows for loss compensation or signal level optimization. The VDCC pin controls the data output cross-point & duty cycle. The HMC847LC5 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.
