HMC850LC3TR

Clock Buffers, Drivers Overview

The HMC850LC3TR is a 1:2 fanout buffer designed for high-speed signal distribution. It supports data transmission rates up to 28 Gbps and clock frequencies as high as 20 GHz. The device features differential CML inputs and outputs, which are DC coupled and internally terminated with 50-ohm resistors. It operates from a single -3.3V DC supply (range -3.0V to -3.6V) and dissipates approximately 315 mW. Key electrical parameters include a propagation delay of 75 ps, rise/fall times of 16/15 ps, and a programmable output voltage swing ranging from 600 mV to 1100 mV via the VR pin.

Clock Buffers, Drivers Procurement Notes

Verify the package type matches the design requirements, as the datasheet specifies a ceramic LCC-16 package while distributor listings may reference SMT variants. Confirm the moisture sensitivity level (MSL 3) and handling precautions during assembly. Ensure the ordering suffix corresponds to the required tape and reel or cut tape format. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm current production status.

Clock Buffers, Drivers Selection Notes

Select this component when a 1:2 fanout buffer is required for signals exceeding 20 GHz. The internal 50-ohm terminations simplify PCB layout by eliminating external matching components. The programmable VR pin allows for adjusting output amplitude to compensate for trace loss or optimize signal levels. Ensure the system can provide a stable negative voltage supply within the -3.0V to -3.6V range.

Clock Buffers, Drivers Part Context

The HMC850LC3 belongs to the HMC850 series of high-speed logic devices manufactured by Analog Devices Inc. It is functionally equivalent to the HMC850LC3, with the TR suffix indicating the specific packaging configuration (Tape & Reel). This family is designed for applications requiring precise timing and high-frequency signal integrity in compact surface-mount packages.
