HD Surveillance
Selector Guide
Semtech is designing the future of HD surveillance with highly integrated products, enabling all-digital HD video surveillance
transmission with industry leading cable reach performance and the highest image delity.
FEATURING New HD-VLC Solutions
secure
Semtech’s next generation of high-performance, all-digital HD video connectivity
solutions for surveillance with integrated HD-VLC™ provide unprecedented levels of cable
reach performance and enable long-distance transmission of high quality HD digital video.
e High-Denition Visually Lossless CODEC (HD-VLC™) has been specically
developed to allow both 720p and 1080p high-denition video to be transmitted at lower
data rates over conventional CCTV coaxial cables. Combined with Semtech’s industry-
leading cable equalizer and CDR technology, cable distances can be extended up to four
times the reach of existing HD-SDI and HDcctv 1.0 products, and up to two times the
reach of other VLC-based products.
Applications
• HD video surveillance cameras
• Digital video recorders (DVR)
• HD monitors & displays
• Video repeaters
• Cable extenders

TRANSMITTER
e GV7700 is a serial digital video transmitter for High-
Denition component video. With integrated cable driving
technology, the GV7700 is capable of transmitting HD video at
a compressed 270Mb/s and 540Mb/s, or uncompressed video at
1.485Gb/s and 2.97Gb/s over 75W coaxial cable, or dierentially
over 100W twisted pair cable.
