HMC674LC3CTR

Overview

The HMC674LC3CTR is a silicon germanium monolithic ultrafast latched comparator featuring RSPECL output drivers. It supports 10 Gbps operation with a typical propagation delay of 85 ps and an equivalent input bandwidth of 9.3 GHz. The device operates on a +3.3 V input supply, +2.0 V output supply, and -3.0 V negative supply, dissipating 140 mW. It includes resistor-programmable hysteresis and differential latch control inputs within a 16-terminal ceramic leadless chip carrier package.

Feature Summary

• Features reduced swing positive emitter-coupled logic (RSPECL) output stages capable of directly driving 400 mV into a 50 Ω load.
• Incorporates a high-speed latch mechanism allowing operation in either transparent track mode or hold mode via differential latch enable inputs.
• Supports programmable hysteresis through an external resistor connected to the HYS pin for noise immunity adjustment.

Applications

• Automatic test equipment (ATE)
• High speed instrumentation
• Digital receiver systems
• Pulse spectroscopy
• Clock and data restoration

Procurement Notes

Verify the specific suffix 'CTR' indicates reel packaging when sourcing from distributors. Confirm the component matches the Analog Devices manufacturer identification. Ensure the ordering part number aligns with the required 16-terminal LCC package variant rather than the plastic LFCSP version.

Selection Notes

Select this component for applications requiring sub-100 ps propagation delay and support for 10 Gbps data rates. The device is suitable for designs needing integrated latch functionality and adjustable hysteresis without external discrete components. Verify power supply requirements match the specified +3.3 V, +2.0 V, and -3.0 V rails.

Part Context

This part belongs to the HMC674 series of ultrafast comparators manufactured by Analog Devices. It utilizes silicon germanium technology to achieve high-speed performance. The device is functionally identical to the HMC674LP3E but differs in package construction, utilizing a ceramic leadless chip carrier instead of a plastic lead frame chip scale package.
