Product Overview
The GV7700-INE3 is a long-reach HD-VLC™ video transmitter from Semtech. It serializes parallel digital video streams for transmission over coaxial or UTP cables. Using proprietary HD-VLC encoding technology, it delivers HD video over extended cable distances without expensive repeaters. Equipped with integrated cable driver and programmable equalization, this 84-QFN IC offers a cost-effective solution for surveillance, machine vision and medical display systems.
Core Advantages
Ultra-Long Reach HD Video Transmission
Adopts HD-VLC™ serialization to transmit HD video over 75Ω coaxial or UTP cables, exceeding standard HD-SDI transmission limits.
Integrated Cable Driver with Pre-Emphasis
Built-in differential cable driver with adjustable swing and programmable pre-emphasis to offset cable high-frequency attenuation and reduce signal loss.
Low-Cost Infrastructure Upgrade
Allows legacy analog CCTV cabling to be upgraded to HD digital video without full cable replacement, cutting project deployment costs.
Stable Signal & Low Jitter
Integrated PLL and jitter suppression circuitry ensures strong noise immunity and stable timing over long transmission wiring.

Frequently Asked Questions
Q1: What is HD-VLC technology and how does GV7700-INE3 work with it?
A: HD-VLC is Semtech proprietary serialization technology. GV7700-INE3 converts parallel video into low symbol-rate streams, enabling long-distance HD video transmission over coaxial cables and reducing high-frequency signal attenuation.
Q2: Can GV7700-INE3 transmit audio and control signals alongside video?
A: Yes. It supports multiplexed auxiliary channels. Embedded audio, PTZ control commands (RS-485/coaxial telemetry) and status signals can be transmitted together with HD video over one cable.
Q3: What do suffix -INE3 stand for on GV7700-INE3?
A: IN means operating temperature range -20°C ~ +85°C. E3 represents lead-free RoHS-compliant eco packaging. The device adopts 84-pin QFN housing.
Q4: Which matching receiver chip works with GV7700-INE3?
A: This transmitter pairs with corresponding Semtech HD-VLC deserializer IC on the receiving end to restore original parallel digital video signals for DVR or display equipment.
Q5: What video standards and bit rates does GV7700-INE3 support?
A: It supports SD-SDI, HD-SDI, 3G-SDI and HDcctv 1.0, with auto-adaptive rates: 270Mb/s, 540Mb/s, 1.485Gb/s and 2.97Gb/s.
Q6: What cables can be used for signal transmission?
A: Compatible with 75Ω coaxial cable and 100Ω Cat-5e/Cat-6 UTP twisted pair cables for different transmission distance demands.
Q7: What typical application scenarios are suitable for GV7700-INE3?
A: Widely used in HD surveillance cameras, industrial machine vision, medical imaging display and legacy analog cabling upgrade projects.
