HMC857LC5TR-R5

Overview

The HMC857LC5TR-R5 is a 2x2 crosspoint switch supporting 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 via the VR pin. Propagation delay is 117 ps. It is housed in a 32-lead ceramic 5x5 mm SMT package.

Feature Summary

• Supports high-speed data transmission up to 14 Gbps
• Features programmable output voltage level control for signal optimization
• Provides flexible routing with differential or single-ended input/output configurations

Applications

• SONET OC-192 and 10 GbE systems
• 16G Fiber Channel applications
• Networking and storage infrastructure
• Dual 2:1 selector implementations
• 1:2 fanout with input multiplexing

Procurement Notes

Verify the specific suffix TR-R5 against official documentation to confirm reel packaging specifications. Ensure compatibility with the required operating temperature range of -40°C to +85°C. Confirm that the 32-lead ceramic package aligns with your PCB footprint requirements. Validate RoHS compliance status through current manufacturer declarations before integration.

Selection Notes

Select this component when designing circuits requiring high-speed signal routing at data rates up to 14 Gbps. The integrated output level control allows for loss compensation without external components. Consider the 32-lead ceramic package size for board space constraints. Ensure the design supports the -3.3 V single supply requirement and manages thermal dissipation within the specified junction temperature limits.

Part Context

The HMC857LC5 belongs to the HMC857 series of analog and digital crosspoint ICs manufactured by Analog Devices (formerly Hittite Microwave Corporation). This series is designed for high-performance communication and networking applications requiring reliable signal switching at multi-gigabit speeds.

Replacement Considerations

Consult official datasheets for direct substitutes within the HMC857 family. Verify pin compatibility and electrical specifications before replacing.
