HMC857LC5

Overview

The HMC857LC5 is a 2x2 Crosspoint Switch designed for data transmission rates up to 14 Gbps and selector port operation up to 14 GHz. It operates from a single -3.3 V supply with typical power consumption of 345 mW. The device features differential or single-ended inputs/outputs, fast rise/fall times of 21 ps, and programmable differential output voltage swing ranging from 475 to 1200 mVp-p. Propagation delay is typically 117 ps. It is housed in a 32-lead ceramic 5 x 5 mm SMT package.

Procurement Notes

Verify the specific ordering suffix against official Analog Devices documentation to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity levels prior to procurement. Ensure the supplier provides valid traceability documents matching the manufacturer's part number and lot codes.

Selection Notes

Select this component when designing systems requiring a 2x2 crosspoint switch capable of handling 14 Gbps signals. Consider the programmable output voltage feature for signal level optimization or loss compensation. Verify that the system can accommodate the 32-lead ceramic SMT package dimensions and thermal requirements.

Part Context

The HMC857LC5 belongs to the Hittite Microwave Corporation (now Analog Devices) high-speed logic product line. It is specifically engineered as a surface-mount technology (SMT) crosspoint switch. The device integrates on-chip termination for CML inputs and supports both DC and AC coupling configurations.
