HMC958LC5

HMC958LC5 v05.0914 HIGH SPEED LOGIC - SMT 14 Gbps, 4:1 SELECTOR WITH PROGRAMMABLE OUTPUT VOLTAGE Typical Applications Features The HMC958LC5 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: 17 ps • 4:1 Multiplexer Low Power Consumption: 294 mW typ. • Built-In Test Programmable Differential Output Voltage Swing: 525 - 1300 mVp-p • Broadband Test & Measurement Propagation Delay: 121 ps Single Supply: -3.3 V 32 Lead Ceramic 5 x 5 mm SMT Package: 25 mm 2 Functional Diagram General Description The HMC958LC5 is a 4:1 Selector 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. All differential inputs to the HMC958LC5 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 HMC958LC5 also features an output level control pin, VR, which allows for loss compensation or signal level optimization. The HMC958LC5 operates from a single -3.3 V supply and is available in a ROHS-compliant 3x3 mm SMT package.
