Video Input Processor (VIP)
SAA7111
Notes
1. For board design without boundary scan implementation (pin compatibility with the SAA7110) connect the TRST pin
to ground.
2. This pin provides easy initialization of BST circuit. TRST can be used to force the TAP (Test Access Port) controller
to the Test-Logic-Reset state (normal operation) at once.
3. In accordance with the
IEEE1149.1 standard the pads TCK, TDI, TMS and TRST are input pads with an internal
pull-up transistor and TDO a 3-state output pad.
4. All pin names that carry an ‘overscore’ have been renamed due to Philips pin name conventions. In previous data
sheet versions these pins were marked by the suffix ‘N’, e.g. TRST = TRSTN.
VPO (9 to 0)
53 to 62
42 to 51
O
Digital VPO-bus output signal; lower bits of the 16-bit YUV-bus or the
16-bit RGB-bus output signal. The output data rate, the format and
multiplexing schema of the VPO-bus are controlled via I2C-bits
OFTS0 and OFTS1. With I2C-bit VIPB = 1 the digitized input signals
(AD1 [1 and 0] and AD2 [7 to 0]) are connected to these outputs.
FEI
63
52
I
Fast enable input signal (active LOW); this signal is used to control
fast switching on the digital YUV-bus. A HIGH at this input forces the
IC to set its Y and UV outputs to the high impedance state; note 4.
GPSW
64
53
O
General purpose switch output; the state of this signal is set via
I2C-bus control and the levels are TTL compatible.
XTAL
65
54
O
Second output terminal of crystal oscillator; not connected if external
clock signal is used.
XTALI
66
55
I
Input terminal for 24.576 MHz crystal oscillator or connection of
external oscillator with CMOS compatible square wave clock signal.
VSS1
67
56
GND
Digital ground for positive supply voltage 1.
VDD1
68
57
P
Positive digital supply voltage 1 (+5 V).
