Product details
Overview
HMC745LC3TR-R5 from Analog Devices is a high-speed differential XOR/XNOR logic gate IC designed for 13 Gbps serial data transmission and 13 GHz clock distribution. It features programmable differential output voltage swing (600–1200 mVp-p), 95 ps propagation delay, 21 ps rise time, and operates from a single 3.3 V supply in a 3 mm × 3 mm ceramic LCC package.
For engineers reviewing the HMC745LC3TR-R5 datasheet, HMC745LC3TR-R5 pinout, HMC745LC3TR-R5 application, or HMC745LC3TR-R5 equivalent, key selection criteria include its 50 Ω on-chip input/output termination, VR-controlled output level tuning, low jitter (0.2 ps rms random), and compatibility with RF ATE and broadband test systems requiring precise high-frequency logic gating.
Technical Context
The HMC745LC3TR-R5 implements a true differential XOR/XNOR function accepting two 50 Ω-terminated differential input pairs (AN/AP and BN/BP) and delivering one differential output pair (DP/DN). Its output driver stage supports both single-ended and differential signaling with tunable swing via the VR control pin.
All I/Os are internally terminated to VCC at 50 Ω, enabling direct connection to 50 Ω–to–VCC systems without external resistors. The device uses a 3.3 V supply only, with no negative or auxiliary rails required, and maintains stable performance across −40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Data Rate | 13 Gbps - supports NRZ serial links up to OC-192/STM-64 and 100G Ethernet PAM4 precursors. |
| Propagation Delay | 95 ps - enables tight timing budgets in multi-stage high-speed logic paths. |
| Rise/Fall Time | 21 ps / 19 ps - preserves signal integrity for >13 GHz fundamental content. |
| Output Swing Range | 600–1200 mVp-p differential - adjustable via VR pin to compensate for PCB loss or match receiver thresholds. |
| Input Termination | 50 Ω to VCC - eliminates need for external biasing or AC-coupling in most 50 Ω systems. |
| Jitter (Random) | 0.2 ps rms - meets stringent BER requirements for 13 Gbps PRBS31 eye opening. |
| Supply Voltage | 3.0–3.6 V (typ. 3.3 V) - compatible with standard logic supply rails and low-noise LDOs. |
Pinout & Package
The HMC745LC3TR-R5 is housed in a 16-terminal, RoHS-compliant ceramic leadless chip carrier (LCC) measuring 3 mm × 3 mm with an exposed pad that must be soldered to ground.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1,4,5,8,9,12,14) | Signal & Supply Ground | Multiple dedicated ground terminals minimize return path inductance for high-frequency operation. |
| VCC (Pins 2,3,13,16) | Positive Supply | Four independent VCC pins reduce supply impedance and improve PSRR at 13 GHz. |
| AN/AP (Pins 2,3) | Differential Input A | True differential pair with internal 50 Ω termination to VCC; accepts clock or data signals. |
| BN/BP (Pins 6,7) | Differential Input B | Second differential input pair, fully symmetric to AN/AP for balanced XOR/XNOR operation. |
| DN/DP (Pins 10,11) | Differential Output | Programmable-swing differential output pair, 50 Ω terminated to VCC, optimized for 100 Ω differential loads. |
| VR (Pin 15) | Output Level Control | Analog voltage input (2.1–3.7 V) sets differential output amplitude per Figure 10 of datasheet. |
| EPAD | Exposed Thermal Pad | Must be connected to PCB ground plane for thermal dissipation and RF reference stability. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed differential logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC855LC3TR-R5 | Same 16-pin LCC package and 3.3 V supply, but optimized as a D-type flip-flop (not XOR/XNOR); 100 ps tpd, 22 ps rise time. | Used in edge-triggered sampling rather than combinatorial logic; lacks VR-controlled output swing. | Select when synchronous latching is required instead of combinational gating. |
| HMC987LP5E | 5-bit programmable delay line (not logic gate); 16-pin QFN, 3.3 V, 13 GHz bandwidth, 100 fs resolution. | Provides fine-grained timing adjustment, not Boolean logic; no XOR/XNOR functionality. | Choose for skew calibration or phase alignment, not logic evaluation. |
Compared with HMC745LC3TR-R5, the HMC855LC3TR-R5 serves sequential logic needs with identical packaging and speed class but no programmable swing, while the HMC987LP5E addresses precision delay rather than logic function-neither is pin- or function-compatible, and each targets distinct signal-path roles in high-frequency systems.

FAQ
What is the maximum data rate supported by the HMC745LC3TR-R5?
The HMC745LC3TR-R5 supports a maximum data rate of 13 Gbps, verified under PRBS31 testing conditions with 13 GHz clock inputs. This rating reflects its capability to reliably transmit NRZ-encoded serial data with sufficient eye opening and jitter margin for high-speed communication links and test equipment interfaces.
Does the HMC745LC3TR-R5 require external termination resistors?
No, the HMC745LC3TR-R5 does not require external termination resistors. All inputs (AN/AP, BN/BP) and outputs (DN/DP) feature internal 50 Ω terminations to VCC, enabling direct interface with standard 50 Ω–to–VCC systems. External resistors are only needed if interfacing with 50 Ω–to–ground configurations, where dc-blocking capacitors would also be used.
How is the output voltage swing controlled on the HMC745LC3TR-R5?
The output voltage swing of the HMC745LC3TR-R5 is controlled via the VR pin (Pin 15), which accepts an analog voltage from 2.1 V to 3.7 V. As shown in Figure 10 of the datasheet, this voltage linearly adjusts the differential output amplitude between 600 mVp-p and 1200 mVp-p, allowing real-time optimization for channel loss or receiver threshold matching.
What package type and dimensions does the HMC745LC3TR-R5 use?
The HMC745LC3TR-R5 uses a 16-terminal ceramic leadless chip carrier (LCC) package designated E-16-1, measuring 3.05 mm × 3.05 mm × 0.90 mm with a 1.50 mm × 1.50 mm exposed thermal pad. This RoHS-compliant package is qualified to MSL Level 3 and supports reflow soldering per JEDEC J-STD-020.
Can the HMC745LC3TR-R5 operate with a supply voltage other than 3.3 V?
Yes, the HMC745LC3TR-R5 operates over a supply voltage range of 3.0 V to 3.6 V, with typical performance specified at 3.3 V. Electrical characteristics-including propagation delay, rise/fall time, and output swing-are characterized across this full range, enabling use with tightly regulated 3.3 V rails or slightly derated supplies in thermally constrained environments.
