HMC857LC5

HMC857LC5 v02.0111 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. • 1:2 Fanout with Input Mux Programmable Differential Output Voltage Swing: 475 - 1200 mVp-p Propagation Delay: 117 ps Single Supply: -3.3 V 32 Lead Ceramic 5 x 5 mm SMT Package: 25 mm2 Functional Diagram General Description The HMC857LC5 is a 2x2 Crosspoint Switch designed 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. ic 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 groundterminated 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 ROHScompliant 3x3 mm SMT package.
