Product details
Overview
HMC678LC3CTR-R5 from Analog Devices (formerly Hittite Microwave) is a high-speed 2:1 selector IC designed for serial data routing in test instrumentation and broadband communication systems. It supports up to 13 Gbps data rate, 13 GHz select port operation, differential or single-ended outputs, and programmable output voltage swing (600–1200 mVpp) via VR pin - enabling loss compensation in high-frequency PCB traces.
For engineers reviewing the HMC678LC3CTR-R5 datasheet, HMC678LC3CTR-R5 pinout, HMC678LC3CTR-R5 application, or HMC678LC3CTR-R5 equivalent, key selection criteria include its -3.3 V single-supply operation, 19/18 ps rise/fall times, 125 ps propagation delay, and 16-lead 3×3 mm ceramic SMT package optimized for RF ATE and serial data transmission up to 13 Gbps.
Technical Context
The HMC678LC3CTR-R5 implements a current-mode logic (CML) 2:1 multiplexer with fully differential internal architecture. Its SP/SN select inputs control routing of AP or BP single-ended data inputs to the DP/DN differential output pair, with set-up/hold time of only 6 ps and deterministic jitter under 2 psp-p at 12.5 GHz.
All inputs are internally 50 Ω terminated to ground and support AC/DC coupling; outputs drive 50 Ω loads directly or via DC-blocking capacitors. The VR pin enables precise output amplitude tuning across temperature and supply voltage variations, critical for maintaining signal integrity in high-speed interconnects.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed 2:1 selector applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC853LC3TR | Higher max data rate (28 Gbps), same 3×3 mm package, requires -3.3 V and -5.2 V supplies | Targeted at next-gen 25G+ optical and microwave test systems where higher bandwidth is mandatory | Select HMC853LC3TR only if >13 Gbps operation is required and dual-supply design is acceptable |
| ADCLK948BCPZ | 8:1 LVDS multiplexer, 12.5 GHz max, 3.3 V supply, different pinout and control interface | Used in clock distribution and fanout applications rather than data path selection | Choose ADCLK948BCPZ when routing multiple clock domains, not high-speed serial data streams |
Compared with HMC853LC3TR and ADCLK948BCPZ, the HMC678LC3CTR-R5 offers optimal trade-off of 13 Gbps performance, single -3.3 V supply, and programmable output swing in a compact ceramic package - making it uniquely suited for cost-sensitive, power-constrained RF ATE and serial data routing where exact 13 Gbps compliance is required.

FAQ
What is the maximum data rate supported by the HMC678LC3CTR-R5?
The HMC678LC3CTR-R5 supports a maximum data rate of 13 Gbps under specified conditions (TA = +25°C, Vee = -3.3 V). This rating is validated using 215−1 PRBS patterns and confirmed by eye diagram analysis on test equipment such as the Agilent N4903A J-Bert. The HMC678LC3CTR-R5 maintains this performance across its full operating temperature range (-40°C to +85°C).
How does the VR pin function on the HMC678LC3CTR-R5?
The VR pin on the HMC678LC3CTR-R5 controls differential output voltage swing from 600 mVpp to 1200 mVpp. It accepts an external DC voltage (typically -1.2 V to 0 V) or can be biased via a resistor to ground, using the formula V0(R) = 1.2 / (2.1 + R), where R is in kΩ. This feature allows real-time compensation for channel loss in the HMC678LC3CTR-R5's target applications.
What package type and footprint does the HMC678LC3CTR-R5 use?
The HMC678LC3CTR-R5 uses a 16-lead ceramic surface-mount package measuring 3×3 mm with an alumina body and gold-over-nickel plating. Its outline drawing specifies non-cumulative lead spacing, 0.05 mm max package warp, and mandatory soldering of the exposed base to Vee. The HMC678LC3CTR-R5 is RoHS compliant and rated MSL3 for moisture sensitivity.
Can the HMC678LC3CTR-R5 operate with single-ended outputs?
Yes, the HMC678LC3CTR-R5 supports both differential and single-ended output configurations. When used single-ended, the DP or DN pin drives a 50 Ω load to ground, delivering 550 mVp-p output swing. No external termination is required due to on-chip 50 Ω matching, and DC blocking capacitors may be added if the receiving system references 50 Ω to a non-ground DC voltage.
What is the supply voltage requirement for the HMC678LC3CTR-R5?
The HMC678LC3CTR-R5 operates from a single negative supply of -3.3 V, with allowable range from -3.6 V to -3.0 V. Power supply current is typically 76 mA, resulting in ~250 mW total power dissipation. The device is not compatible with positive supply rails or dual-supply configurations - all functionality depends on correct biasing of the Vee pin at -3.3 V.
