Today we explain in detail the HDMI audio and video signal extension amplifier products AG7120 and AG7220, their performance description, parameter characteristics, performance comparison, application methods and design circuits.
The AG7120 chip is a digital video interface (DVI) or high-definition multimedia interface (HDMI) re driver that automatically compensates for HDMI/DVI cable loss. The maximum bandwidth is 3.4Gbps per channel, and deep color support is provided. Its low-power operation does not require an external power supply. The AG7120 is space-saving, QFN24 package, and works in an extended temperature range of 0°C to +70°C.
The AG7220 chip is a single-chip solution for high-definition multimedia. It is used for HDMI cables with HDMI2.0 devices to maintain high-bandwidth data interface (HDMI) RE drivers on thinner or longer devices. Its maximum bandwidth is 6Gbps per channel and can support video performance up to 4K2K@60Hz resolution. With Algortec's advanced green design, AG7220 can support functional replenishment without external power supply. Compared with traditional passive cables, with AG7220, HDMI cable manufacturers can provide thinner or longer HDMI 2.0 cables with the same video performance.
AG7120 and AG7220 are mainly used in:
Long cable
HDMI/DVI cable extension cable
HDMI/DVI active cable assembly
projector
High-definition displays and other equipment that need to extend and amplify the video signal;
