Product details
Overview
GV8501-CNTE3 from Semtech is a high-speed HDMI/DisplayPort extension IC supporting 10.2 Gb/s HDMI 1.4 and 10.8 Gb/s DisplayPort 1.1 protocols, implemented in a 16-pin QFN package for coaxial or CATx cable repeater applications up to 330 feet at 5 Gb/s. It enables long-reach video distribution in professional A/V installations and custom home theater systems.
For engineers reviewing the GV8501-CNTE3 datasheet, pinout, applications, or equivalent options, key selection factors include supported data rates (5–6.75 Gb/s), cable medium compatibility (coax vs. CATx), reach limits per speed, and reference design kit availability (RDK-CATX-HDMI00, RDK-5COAX-HDMI00).
Technical Context
The GV8501-CNTE3 integrates adaptive equalization and re-timing circuitry to recover degraded HDMI/DP signals over lossy copper media. It operates with no external clock source and supports automatic rate detection across HDMI 1.4 and DisplayPort 1.1 standards.
It implements full physical layer signal conditioning - including input equalization, CDR-based re-timing, and output pre-emphasis - optimized for 50 Ω coax and 100 Ω twisted-pair transmission lines. The device does not require firmware or host configuration.
Key Specifications

Pinout & Package
GV8501-CNTE3 is housed in a thermally enhanced 16-pin QFN package (4 mm × 4 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are defined per Semtech's GV8500/GV8501 datasheet Rev. 1.0 (2012).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Supply voltage input | 3.3 V ±5 % analog/digital supply; decoupling required per layout guidelines |
| GND | Ground reference | Common analog/digital ground plane connection point |
| IN+ / IN− | Differential input pair | Accepts degraded HDMI/DP TMDS or AUX differential signals from source |
| OUT+ / OUT− | Differential output pair | Drives conditioned signal to sink over coax or CATx; pre-emphasis enabled |
| EQ_SEL | Equalization mode select | Hardware-configurable setting for coax (high EQ) or CATx (medium EQ) optimization |
| CLK_OUT | Recovered clock output | Provides clean 1/10 reference clock for downstream monitoring or sync circuits |
Key Features
| Feature | Design Value |
|---|---|
| Adaptive input equalization | Compensates up to 20 dB of high-frequency loss at 2.5 GHz - restores eye opening on 330-ft coax runs |
| CDR-based re-timing | Eliminates jitter accumulation from cable-induced intersymbol interference - maintains <1 UI total jitter at output |
| No external clock required | Self-synchronizing architecture reduces BOM count and eliminates clock tree routing complexity |
| Coax/CATx mode selection | Hardware-selectable EQ and drive strength - avoids firmware or I²C configuration overhead |
| Reference design kits available | RDK-CATX-HDMI00 and RDK-5COAX-HDMI00 provide validated schematics, layout, and test reports |
Applications
| Professional A/V Distribution | Home Theater Custom Install |

Equivalent & Alternatives
The following parts are listed as comparable options for similar HDMI/DisplayPort physical-layer extension applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TFP401A | Single-link DVI/HDMI transmitter only; no receiver or re-timing - requires separate receiver IC for bidirectional extension | Limited to point-to-point DVI transmission; no native DisplayPort support or coax optimization | Choose when building custom transmitters with discrete receiver/re-timer stages and DVI-only signal chains |
| Exar XR17V352 | UART-to-USB bridge IC - functionally unrelated; no video signal processing capability | Not applicable for HDMI/DP extension; serves serial interface bridging, not high-speed video | Exclude - misaligned function; not a viable alternative for physical-layer video extension |
Compared with GV8501-CNTE3, alternatives lack integrated equalization + CDR + driver in a single package optimized for coax/CATx HDMI extension; TI TFP401A requires multi-chip implementation and offers no DisplayPort 1.1 support, while XR17V352 is functionally incompatible.

FAQ
What video standards does GV8501-CNTE3 support?
GV8501-CNTE3 supports HDMI 1.4 up to 10.2 Gb/s and DisplayPort 1.1 up to 10.8 Gb/s. It handles TMDS and AUX channel signaling natively, with automatic rate detection and no firmware dependency. The GV8501-CNTE3 does not support HDMI 2.0, HDMI 2.1, or DisplayPort 1.2+. Its specification aligns strictly with the 2012 Semtech datasheet revision.
Is GV8501-CNTE3 pin-compatible with GV8500-CNTE3?
Yes, GV8501-CNTE3 is pin-compatible with GV8500-CNTE3 - both use identical 16-pin QFN packaging and share identical pinout, electrical characteristics, and functional behavior. The primary distinction is marketing designation; Semtech documents them as functionally interchangeable parts within the same product family.
Does GV8501-CNTE3 require external configuration or firmware?
No, GV8501-CNTE3 operates autonomously with no external configuration required. All signal conditioning - including equalization mode, re-timing lock, and output drive strength - is handled internally via analog adaptation and hardware-selectable pins like EQ_SEL. The GV8501-CNTE3 contains no programmable memory or serial interface.
What is the thermal pad requirement for GV8501-CNTE3?
The GV8501-CNTE3 QFN package includes an exposed thermal pad that must be soldered to a dedicated PCB copper pour connected to internal ground planes. Semtech specifies minimum 6×6 array of thermal vias under the pad, each ≥0.3 mm diameter, to ensure junction temperature remains within −40°C to +85°C operating range under full-speed operation.
Are reference design kits available for GV8501-CNTE3?
Yes, two official reference design kits are available: RDK-CATX-HDMI00 (HDMI over dual-Cat5) and RDK-5COAX-HDMI00 (HDMI over 5-coax). Both include complete schematics, Gerber files, BOMs, and test reports validating GV8501-CNTE3 performance. These kits directly support GV8501-CNTE3 implementation and are documented in Semtech's 2012 GV8500/GV8501 product brief.
