A20 PCI Backplane Board

The A20 PCI Backplane board consists of the following connectors and

circuitries:

The J100, J110, and J120 connectors are PCI slots for 5 V. The J130 connector is

a PCI slot for 3.3 V and is reserved in the future. The J100 connector is the

system slot and is used to install the CPU board (single board computer: SBC).

The J110 and J120 connectors are used to install the A12 Main board and the

A180 QAM Modulator board.

The PWR_Button line (Pins 9 and 10 of J310) of the SBC is connected to the

power switch on the Keypad board through the Front-Panel Processor board.

When the power switch is pressed, the SBC causes the PSON# signal to go low.

When the PSON# signal becomes low, Q10 turns on and +12 V main power is

also on. When the power switch is pressed again, its status is sent to BIOS and

the PSON# signal turns high. This circuit includes a +12 V to +5 V DC-DC

converter, a +12 V to +3.3 V converter, and a +12 V to --12 V converter.

There are four connectors in the interconnect circuit: J230, J240, J290, and J310.

J230 is used to connect the board to the LCD interface on the CPU board. J290

is used to connect the board to COM2 on the CPU board. J310 is used to connect

the board to the hard disk drive LED and reset/power button on the CPU board.

J240 is used to connect the board to the Front-Panel Processor board. This circuit

also has an RS-232C level converter.

U700 (PIC Micro) controls the internal fan revolution. It gets the temperature

data from the sensors (U720 and U730) through 12C BUS and controls the

supply voltage to the fan (7 V to 11.5 V).

The IEEE1394 interface consists of the 1394b link-layer device (U110), cable

transcriver/arbiter (U120), oscillator (Y100), serial EEPROM (U140), regulators

(U130 and U230), and IEEE1394b connector (J140).
