Behavioural mixed-signal modelSiI9022ACNUsii9022a
SiI9022A HDMI transmitter
HDMI 1.4 transmitter: 24-bit RGB parallel video in (D0–D7 blue, D8–D15 green, D16–D23 red, IDCK, DE, HSYNC, VSYNC), TMDS out to an HDMI receptacle. Control over I²C at 0x39 (CI2CA low): identification B0h, power states, hot-plug interrupt (INT open drain), and the sink's EDID passed through from DSCL/DSDA. RESET# low ≥ 100 µs after power. Supplies: CVCC12 / AVCC12 1.2 V, IOVCC 3.3 V; HPD needs an external 10 kΩ pull-down. Audio inputs are not modelled.

Simulation model
A behavioural model implements the interface of the chip (registers, protocol, timing) at its pins. The pins are connected to the analog circuit like CMOS pins.
