Aiwa IC-DP200, Service Manual

Page: 23 / 33

– 23 –
17 FODD O FODD: Odd field flag. Asserted high during the odd field, low during the even field. (Not used)
18 HREF O
HREF: Horizontal window reference output.
HREF is high during the active pixel window, otherwise low.
19 ~ 26 UV7 ~ UV0 O UVn: Digital output UV bus. UVn used for 16-bit operation for outputting chrominance data.
27 XCLK1 I
XCLK1 and XCLK2 are the input/output of the on-chip video oscillator.
28 XCLK2 O
Nominal crystal clock frequency is 27MHz.
If an external clock is used, input to XCLK1, leave XCLK2 unconnected. (XCLK2 = Not used)
29 DVDD – Digital power (+5V) pin.
30 DGND – Digital ground connection.
31 DOGND – Digital output ground connection.
32 DOVDD – Digital I/O power (+5V) pin.
PCLK: Pixel clock output. By default, data is updated at the falling edge of PCLK
33 PCLK O and is stable at its rising edge. PCLK runs at the pixel rate in 16-bit bus operations
and twice the pixel rate in 8-bit bus operations.
Yn: Digital output Y bus. In a 16-bit operation, the luminance data is clocked out of this bus
34 ~ 41 Y7 ~ Y0 O at the rate of one byte per pixel. In 8-bit operation, the luminance data and the chrominance data
is multiplexed to this bus.
42 CHSYNC O CHSYNC: Digital output for either composite sync or horizontal sync signal.
43AGND – Analog ground connection.
44 AVDD – Analog power (+5V) pin.
45 SCL I I
2
C serial clock input with schmitt trigger.
46 SDA I/O I
2
C serial data, output is open-drain, input with schmitt trigger.
47 MID I Multiple I
2
C slave ID enable. (Not used)
48 SGND – Sensing ground connection
Pin No. Pin Name I/O Description
IC, PCF8576CH
1 NC – Not connected.
2 ~ 7 S34 ~ S39 O LCD segment outputs. (Not used)
8 ~ 9 NC – Not connected.
10 SDA I/O I
2
C bus serial data input/output.
11 SCL I I
2
C bus serial clock input.
12 SYNC I/O Cascade synchronization input/output. (Not used)
13CLK I External clock input. (Not used)
14 VDD – Supply voltage.
15 OSC I Oscillator input. (Connected to VSS)
16 ~ 18 A0 ~ A2 I I
2
C bus subaddress inputs. (Connected to VSS)
19 SA0 I I
2
C bus slave address input, bit 0. (Connected to VSS)
20 VSS – Logic ground.
