IC302
AUDIO CODEC
VH+-1Y
The WM8983 is a low power, high quality stereo codec designed for
portable multimedia applications.
The device integrates preamps for stereo differential mics, and includes
drivers for speaker, headphone and differential or stereo line output.
Advanced on-chip digital signal processing includes a 5-band
equaliser, a mixed signal Automatic Level Control for the microphone or
line input through the ADC as well as a purely digital limiter function for
record or playback.

AV-switch
VHIMM1492BJ-1Y
This IC is a 5-input 2-output AV switch controlled by the I2C BUS devel-
oped for use in television.
Because there are 2 outputs, it supports 2 screens and P-IN-P, and also
supports an external output (monitor) pin.

RS-232C-RECEI/
DRIV
VHIIM3221EIP
The MAX3221E is a single driver, single receiver RS-232 solution oper-
ating from a single Vcc supply. The RS-232 pins provide IEC G1000-4-
2 ESD Protection. The device meets the requirements of TIA/EIA-232-F
and provides the electrical interface between an asynchronous commu-
nication controller and the serial-port connector. The charge pump and
four small external capacitors allow operation from a single 3V to 5.5V
supply.
