Usage

Description

10

BL-C1CE / BL-C1E

Consists of IC101 (CPU), IC202 (ETHER-PHY), T1 (Trans) and CN2 (RJ45).
T1 (Trans) insulates sets and Ethernet.
IC101 (CPU) and IC202 (ETHER-PHY) are connected by a signal called MIIBus which it makes it possible to transmit/receive
Ethernet data.
IC202 has Auto Negotiation Function which changes 100BASE-T or 10BASE-TX automatically.

Transmitting Operation
Electric signal from IC101 is changed to Ethernet data on IC202 and it is sent through T1 from CN2.
Receiving Operation
Ethernet data from CN2 is change to electrical signal on IC202 and it is received by IC101.

The light entered from the lens is converted to the video signal by the CMOS sensor (IC701) equipped on this block.  The
CMOS sensor is IC101 generates timing signals such as PIXCLK, FRAME_VALID, and LINE_VALID by the 16.67MHz-clock
signal entered.  And it is supplied to the CPU (IC101).  The video signal is outputted from DOUT{7:0} to the CPU as the 8bit-
YUV signal.  Various settings of the CMOS sensor are conducted through the two signals, SCLK and SDATA, which are sup-
plied from the CPU.
The rough specifications and the block diagram of the CMOS sensor are shown below.

Operating Power Supply: +2.8V
Package: 24pin CLCC
Optical size:  1/4-inch VGA
Image Sensor and its Process Circuit are installed.
Total Number of Pixels: 649(H) x 489(V) pixels
Available Number of Pixels: 640(H) x 480(V) pixels
Color Filter: RGB Beyer Alignment
Functions: Automatic White Balance and Auto Exposure

BL-C1CE / BL-C1E

Operating Power Supply: 3.3V (3V battery for back up)
Package: 18 pin SOP
Outline of Operation: Stores Clock Data and supplies 32.768 KHz Clock Signal to CPU (IC101).
Backup Battery provides power when power supply is out.

Output Voltage: 3V
Capacity: 220mAh
Outline of Operation: A backup power supply for Real Time Clock (IC302).

LED is controlled by CPU which is mounted on Main Board. Control data is input into LED Control Circuit which is mounted on
Sub Board. (Three color LED is employed.)
