HMC857LC5 v04.0914 14 Gbps, 2 x 2 CROSSPOINT SWITCH WITH PROGRAMMABLE OUTPUT VOLTAGE Typical Applications Features The HMC857LC5 is ideal for: Supports High Data Rates: up to 14 Gbps SONET OC-192 and 10 GbE Differential or Single-Ended Inputs / Outputs 16G Fiber Channel Fast Rise and Fall Times: 21 / 21 ps Networking & Storage Low Power Consumption: 345 mW typ. Programmable Differential Dual 2:1 Selector Output Voltage Swing: 475 - 1200 mVp-p 1:2 Fanout with Input Mux Propagation Delay: 117 ps Single Supply: -3.3 V 2 32 Lead Ceramic 5 x 5 mm SMT Package: 25 mm Functional Diagram General Description The HMC857LC5 is a 2x2 Crosspoint Switch desig- ned to support data transmission rates of up to 14 Gbps and selector port operation up to 14 GHz. The selector routes the differential inputs to either one or both of the desired outputs upon assertion of the appropriately selected port. All differential inputs to the HMC857LC5 are CML and terminated on-chip with 50 Ohms to the positive supply, GND, and may be DC or AC coupled. Outputs can be connected directly to a 50 Ohm ground- terminated system or drive devices with CML logic input. The HMC857LC5 also features an output level control pin, VR, which allows for loss compensation or signal level optimization. The HMC857LC5 operates from a single -3.3 V supply and is available in ROHS- compliant 3x3 mm SMT package. Electrical Specifications, T = +25 C, Vee = -3.3 V, Vr = 0 V A Parameter Conditions Min.
