Product details
Overview
GV8501-CNE3 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 signaling, implemented in a 16-pin QFN package for coaxial or CATx cable repeater applications in professional A/V installations.
For engineers reviewing the GV8501-CNE3 datasheet, pinout, applications, or equivalent options, key selection criteria include signal rate support (up to 10.8 Gb/s), cable reach at 5 Gb/s (330 ft over coax), and compatibility with HDMI 1.4 and DisplayPort 1.1 physical layer protocols.
Technical Context
The GV8501-CNE3 integrates adaptive equalization and re-timing circuitry optimized for lossy STP or coaxial transmission channels, operating across 1.25–5.4 GHz bandwidth with automatic input signal detection and lock-to-data recovery. It supports both AC-coupled differential inputs and outputs compliant with HDMI and DisplayPort voltage swing and common-mode requirements.
Unlike the GV8502 (HDMI-only, 21 Gbps) or GV8502A (DisplayPort-only extension), the GV8501-CNE3 implements dual-standard support with fixed-rate clock recovery and no embedded microcontroller - requiring external configuration via I²C for gain and equalization settings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| HDMI Support | HDMI 1.4 compliant up to 10.2 Gb/s - enables full 4K24 and 1080p60 extended-reach operation |
| DisplayPort Support | DisplayPort 1.1 compliant up to 10.8 Gb/s - supports HBR (High Bit Rate) mode at 2.7 Gb/s per lane × 4 lanes |
| Max Cable Reach (5 Gb/s) | 330 feet over coaxial cable - eliminates need for active fiber or powered mid-span repeaters in retrofit installations |
| Max Cable Reach (6.75 Gb/s) | 150 feet over CATx - defines usable distance for higher-resolution timing without signal degradation |
| Package | 16-pin QFN (3 mm × 3 mm, 0.5 mm pitch) - surface-mount compatible with standard reflow profiles and compact extender PCB layouts |
| Supply Voltage | 3.3 V ±5% - matches standard A/V system power rails and avoids need for auxiliary LDOs |
Pinout & Package
GV8501-CNE3 is housed in a 3 mm × 3 mm, 16-pin QFN package with exposed thermal pad (EP), rated for operation from 0°C to 70°C ambient. Pin 1 is marked by a dot; pins are numbered counter-clockwise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply input | 3.3 V main supply for analog and digital core; requires local 100 nF + 1 µF decoupling |
| GND | Ground reference | Common return for all analog/digital circuits; tied to EP for thermal and noise control |
| IN+ / IN− | Differential data input pair | AC-coupled HDMI/DP input; accepts 100 Ω terminated signals with 0.2–1.2 Vpp swing |
| OUT+ / OUT− | Differential data output pair | Re-timed, equalized output driving 100 Ω coax or twisted-pair; supports DC-balanced TMDS encoding |
| SCL / SDA | I²C interface | Two-wire serial bus for configuring EQ gain, output swing, and lock status reporting |
| LOCK | Signal lock indicator | Open-drain output asserted low when valid data lock is achieved on input stream |
Key Features
| Feature | Design Value |
|---|---|
| Adaptive equalization | Compensates up to 20 dB of channel loss at 2.5 GHz - extends usable cable length without manual tuning |
| Retiming with jitter cleanup | Reduces deterministic jitter below 0.3 UI - ensures HDMI/DP receiver eye compliance after long cable runs |
| Dual-standard protocol handling | Single IC processes both HDMI 1.4 and DisplayPort 1.1 physical layers - reduces BOM count vs. separate solutions |
| I²C programmable configuration | Enables field-adjustable EQ, output amplitude, and power-down modes - supports multiple cable types from one PCB design |
| Lock-detection output | Hardware-level LOCK pin provides real-time status to system controller - eliminates software polling overhead |

Equivalent & Alternatives
The following parts are listed as comparable options for similar HDMI/DisplayPort extension applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GV8500-CNE3 | Identical pinout and electrical specs; differs only in factory-programmed default EQ settings - no functional distinction in schematic or layout | No difference in supported applications or cable reach; both qualified for same RDKs (RDK-CATX-HDMI00, RDK-5COAX-HDMI00) | Select GV8500-CNE3 if legacy firmware expects default EQ profile A; otherwise GV8501-CNE3 is functionally interchangeable |
| TI TFP401APZPR | Single-function HDMI transmitter (not repeater); no re-timing, no equalization, no DisplayPort support; requires external clock and MCU control | Limited to short-range point-to-point HDMI bridging (<15 ft); not suitable for coax/CATx extension beyond 50 ft | Choose only for simple source-side serialization where signal integrity is guaranteed - not a drop-in replacement for GV8501-CNE3 extension roles |
Compared with GV8500-CNE3, the GV8501-CNE3 offers identical hardware functionality but distinct factory EQ initialization; compared with TI TFP401APZPR, it delivers full re-timing, adaptive equalization, and dual-standard support essential for long-reach HDMI/DP extension - making it the only viable option for >100-ft deployments.

FAQ
What video standards does the GV8501-CNE3 support?
The GV8501-CNE3 supports HDMI 1.4 up to 10.2 Gb/s and DisplayPort 1.1 up to 10.8 Gb/s. It handles TMDS-encoded HDMI signals and DisplayPort's 8b/10b encoded streams with automatic protocol detection. The GV8501-CNE3 does not support HDMI 2.0, HDMI 2.1, or DisplayPort 1.2+. Its design targets legacy A/V installations where HDMI 1.4 and DP 1.1 compliance is sufficient.
Is the GV8501-CNE3 pin-compatible with the GV8500-CNE3?
Yes, the GV8501-CNE3 is fully pin-compatible and footprint-compatible with the GV8500-CNE3. Both share identical 16-pin QFN packaging, electrical characteristics, and register map. The only difference lies in factory-default equalization settings - a non-hardware distinction that does not affect PCB layout, schematic symbol, or mechanical integration. The GV8501-CNE3 can replace GV8500-CNE3 without design changes.
Does the GV8501-CNE3 require an external microcontroller?
The GV8501-CNE3 operates autonomously after power-up and does not require an external microcontroller for basic re-timing and equalization. However, an I²C host is needed to read LOCK status, adjust EQ gain, or modify output swing. For unmanaged applications (e.g., fixed-cable-type extenders), default settings suffice - the GV8501-CNE3 will lock and regenerate without firmware intervention.
What is the maximum supported resolution and refresh rate for the GV8501-CNE3?
The GV8501-CNE3 supports up to 1920×1080p60 (5.4 Gb/s) over 330 feet of coax or 150 feet of CATx at 6.75 Gb/s. It does not support 4K resolutions (e.g., 3840×2160) at 60 Hz due to bandwidth limits. At 24 Hz, 4K may be achievable depending on color depth and chroma subsampling, but this is outside the validated spec - the GV8501-CNE3 is characterized and guaranteed only for HDMI 1.4 and DP 1.1 timing profiles.
Can the GV8501-CNE3 be used in new designs despite its "Not Recommended for New Designs" status?
Yes - the "Not Recommended for New Designs" label applies only to Semtech's internal roadmap guidance and does not indicate obsolescence or reliability concerns. The GV8501-CNE3 remains fully available, supported with documentation and reference kits (e.g., RDK-CATX-HDMI00). Aetrix Electronics provides full supply chain continuity for the GV8501-CNE3 in new commercial and industrial A/V projects where its performance and cost align with system requirements.
