HMC675LC3CTR-R5

Overview

The HMC675LC3CTR-R5 is a SiGe monolithic latched comparator featuring an RSCML output stage. It supports 10 Gbps operation with a typical propagation delay of 100 ps and 60 ps minimum pulse width. The device offers 10 GHz equivalent input bandwidth, 80 dB common mode rejection ratio, and 100 mW power dissipation. It includes resistor-programmable hysteresis and differential latch control within a 16-lead SMT package.

Feature Summary

• Features reduced swing CML output drivers designed to directly drive terminated loads.
• Supports configurable operation in either latch mode or tracking comparator mode.
• Includes differential latch control inputs for precise timing acquisition.

Applications

• Automated Test Equipment (ATE)
• High Speed Instrumentation
• Digital Receiver Systems
• Clock & Data Restoration

Procurement Notes

Verify the specific suffix 'R5' against official documentation to confirm reel packaging specifications. Ensure compatibility with the required supply voltages and termination resistors. Confirm that the component meets all necessary environmental standards for the intended deployment environment before finalizing procurement.

Selection Notes

Select this component when high-speed signal comparison with minimal jitter is required. The integrated latch functionality simplifies circuit design for data recovery applications. Consider the low power dissipation and small form factor for dense PCB layouts requiring high-frequency performance.

Part Context

This part belongs to the HMC675 series of ultra-fast comparators manufactured by Analog Devices Inc. It utilizes SiGe technology to achieve high bandwidth and low noise characteristics suitable for demanding RF and microwave applications.

Replacement Considerations

Consult official datasheets for direct pin-compatible alternatives within the same product family. Verify electrical parameter equivalence for propagation delay and output swing before substitution.

FAQ

How is the hysteresis controlled on the HMC675LC3CTR-R5?

Hysteresis is controlled via the HYS pin, which should be connected to Vee with a resistor to add the desired amount of hysteresis.

What are the operating modes of the HMC675LC3CTR-R5?

The device can operate in Track Mode, where the output follows the input, or Latch Mode, where the output holds the comparison result based on the latch enable signals.
