resistor.
40
TEST1 (MST)
I
This pin must be connected to GND.
61
VCLK
I
Video Pixel-Clock input from camera
64
HVALID
I
Video Clock Enable input qualifier. This input pin
should be connected to GND if not used.
62
VSYNC
I
Video Vertical-Sync input signal from camera. This
input pin should be connected to GND if not used.
65
HSYNC
I
Video Horizontal-Sync input signal from camera.
This input pin should be connected to GND if not
used.
63
FID
I
Video Field-ID input signal from camera. This input
pin should be connected to GND if not used.
12 – 13
IO-1 - IO-2
I/O General Programmable I/O pins. Each of these 2 pins
has an Open Drain, and is supposed to be connected
to an external Pull-Up resistor. The host uses these
pins as programmable output ports by writing '0' or
'1'. By writing '1' and read back, the host can use
these pins’ input ports - as this allows any external
source to force the Pull-Up resistor. These outputs
are temporarily set to High-z while in Suspend mode.
38
XIN
I
Crystal Oscillator input pin (12 MHz). Crystal
frequency must provide at least 100 PPM accuracy.
39
XOUT
O
Crystal Oscillator output pin (12 MHz).
1
BLK_FULL
O
"Bulk-FIFO full" indication output signal. This
output signal is normally '0' and is set to '1' when the
ZR36506 Bulk-FIFO is full. This output is
temporarily set to '0' while in the Suspend or Power-
Down position.
2
BLK_EN
I
Bulk Data Enable input. When set to '1', Bulk input
data from the DAT_IN pin is sampled in by falling
edge of BCLK into the ZR36506 Bulk-FIFO.
3
DAT_IN
I
Data Input pin for both Audio CODEC Tx channel
and Bulk Data in. This input pin requires an external
Pull-Up resistor.
4
FS_L
O
Audio Codec Frame-Sync pulse for Left channel.
This signal triggers the beginning of a new audio
sample (left chan). This output is temporarily set to
'0' while in the Suspend or Power-Down position.
5
FS_R
O
Audio Codec Frame-Sync pulse for Right channel.
This signal triggers the beginning of a new audio
