TERMINAL
I/O DESCRIPTION
NAME NO.
HSYNC1 100
HSYNC2 77
O Horizontal synchronization
HSYNC3 58
HSYNC4 39
VSYNC1/PALI1 95
1. VSYNC: Vertical synchronization
VSYNC2/PALI2 76
O
2. PALI: PAL line indicator or horizontal lock indicator. For the PAL line indicator, a 1
VSYNC3/PALI3 57
indicates a noninverted line, and a 0 indicates an inverted line.
VSYNC4/PALI4 38
Power down (active low). A 0 on this pin puts the decoder in standby mode. PDN preserves
PDN 122 I
the value of the registers.
Active-low reset. RESETB can be used only when PDN = 1. When RESETB is pulled low, it
RESETB 121 I
resets all the registers and restarts the internal microprocessor.
SCL 120 I/O I
2
C serial clock (open drain)
SDA 119 I/O I
2
C serial data (open drain)
During power-on reset, this pin is sampled along with pin 117 (I2CA1) to determine the I

C
I2CA0 118 I address the device is configured to. A 10-kΩ resistor should pull this either high (to IOVDD)
or low to select different I

CLK1 103
CLK2 84
O Unscaled system data clock at either 27 MHz or 54 MHz
CLK3 61
CLK4 42
SCLK1 104
SCLK2 85 Scaled system data clock at 27 MHz. This signal can be used to qualify scaled/unscaled
O
SCLK3 62 data when the unscaled system data clock is set to 54 MHz.
SCLK4 43
External clock reference. The user may connect XIN to an oscillator or to one terminal of a
XIN/OSC 124 I crystal oscillator. The user may connect XOUT to the other terminal of the crystal oscillator
XOUT 123 O or not connect XOUT at all. One single 14.31818-MHz crystal or oscillator is needed for
ITU-R BT.601 sampling, for all supported standards.
CH1_OUT[7:0] 105–112 O Decoded ITU-R BT.656 output/YCbCr 4:2:2 output with discrete sync for channel 1
CH2_OUT[7:0] 86–93 O Decoded ITU-R BT.656 output/YCbCr 4:2:2 output with discrete sync for channel 2
CH3_OUT[7:0] 67–74 O Decoded ITU-R BT.656 output/YCbCr 4:2:2 output with discrete sync for channel 3
CH4_OUT[7:0] 48–55 O Decoded ITU-R BT.656 output/YCbCr 4:2:2 output with discrete sync for channel 4
Test-mode select. This pin should be connected to digital ground for correct device
TMS 36 I
operation.
