■ MAJOR COMPONENT PARTS AND THEIR FUNCTIONS
No
IC701
Audio amplifier This activates the headphone or the speaker by receiving I2C audio signal from IC200.
IC801
DSP for sampling the audio This samples the analog signal by the line input and transfers the analog signal to the
digital signal. The transferred signal is sent to IC200 by I2C.
IC501
Port processor of HDM
IC200 and IC1400. Or, this sends signals of two HDMI connectors to IC200 and IC1400.
IC200
Scaler IC chip This receives DP2 signal or HDMI signal, scales or handles by double speed and output the left
half part of QFDH (Quad Full High Definition). The video output format is 960 x 2160.
DP2 signals, these ICs receive QFDH signal and send it to IC1400. At this moment, this reads the data of left half
part of the monitor and displays the data.
part of the monitor. When these ICs input 60Hz HDMI signals, these reads the data of half part of the monitor.
Then, displays the data.
IC401,IC402
Frame memory of IC200 operation
IC1400
Scaler IC chip This receives DP2 signal or HDMI signal, scales or handles by double speed and output the left
half part of QFDH (Quad Full High Definition). The video output format is 960 x 2160. When these ICs input DP2
signals, these ICs receive QFDH signal and display only right half part of the monitor. When these ICs input 30Hz
HDMI signals, these reads the data of all part of the monitor. When these ICs input 60Hz HDMI signals, these
reads the data of half part of the monitor. Then, displays the data.
IC2101,IC2102
Frame memory of IC1400 operation
IC2400
CPLD This controls the sequence of starting up the power, the power of each part of the machine or each IC.
IC2500
Controls the arm microcomputer and the whole system.
This receives the signals from two HDMI connectors and handles and sends them to
PN-K321/K322B
