描述

Chrontel’s CH7103B is a low-cost, low-power semiconductor device that consists of HDMI receiver, three separate 9-bit video Digital-to-Analog Converters (DACs), HDTV(YPbPr) encoder, and audio encoder, which can convert HDMI signals into HDTV outputs with IIS or SPDIF audio output.

The HDMI Receiver integrated is compliant with HDMI 1.4b. With sophisticated MCU and the on-chip flash, CH7103B supports auto-boot and EDID buffer. Leveraging the firmware auto loaded from the on-chip flash, CH7103B can support HDMI input detection, DAC connection detection and determine to enter into Power saving mode automatically.
