Block diagram
LSI, IC, and Memory
• X201 (Crystal)
* Crystal oscillator: 24.5760 MHz
• IC201 (MN195004MFN-1)(Modem data pump)
This LSI provides an interface with the host CPU. It is the heart of the modem. It consists of digital
signal processing circuits.
• IC202 (TR88017) (Analog front end)
An analog front end LSI that provides an interface between the line controller and the MN195004.
It consists of analog circuits. It has two channels of 16-bit A/D and D/A converters.
• FLS201 (4MFASH memory)
A memory for storing the MN195004MFN-1 program. * This program cannot be loaded by the PC
loading method.
• RAM201 (High-speed 1MSRAM)
A memory for storing the MN195004MFN-1 program.
The modem operates by loading the program from the flash memory to the SRAM.
• IC205 (Analog switch IC)
Gain control
Power supply voltages
• D5 VD
• 5 VA/-8 VA
