1.2. U6102 (TPA3124D2PWPR)
Description
The TPA3124D2 is a 15-W(per channel);efficient,class-D audio power amplifier for driving stereo speakers in a single-ended configuration;or a
mono speaker in a bridage-tied-load configuration .The TPA3124D2 eliminates the need for an external heat sink when playing music.
The gain of amplifier is controlled by two gain select pins.The gain selections are 20.26.32and 36dB.
The patented start-up and shutdown sequences minimize pop noise in the speakers without additional circuity.

1.3. U1503 (TMDS261)
Description
The TMDS261 is a two-port digital video interface (DVI) or high-definition multimedia interface (HDMI) switch that allows up to two DVI or HDMI
ports to be switched to a single display terminal. Four TMDS channels, one hot-plug detector, and a digital display control (DDC) interface are
supported on each port. Each TMDS channel supports signaling rates up to 3 Gbps to allow 1080p resolution in 16-bit color depth.
The TMDS261 provides an adaptive equalizer for different ranges of cable lengths. The equalizer automatically compensates for intersymbol
interference [ISI] loss of an HDMI/DVI cable for up to 20 dB at 3 Gbps
