Enhanced Video Input Processor (EVIP)
SAA7111A
RTS0
29
O
Two functions output; controlled by I2C-bus bit RTSE0.
RTSE0 = 0: odd/even eld identication (HIGH = odd eld). RTSE0 = 1: vertical
locked indicator; a HIGH state indicates that the internal Vertical Noise Limiter (VNL)
has locked.
VS
30
O
Vertical sync signal (enabled via I2C-bus bit OEHV); this signal indicates the vertical
sync with respect to the YUV output. The HIGH period of this signal is approximately
six lines if the VNL function is active. The positive slope contains the phase
information for a deection controller.
HREF
31
O
Horizontal reference output signal (enabled via I2C-bus bit OEHV); this signal is used
to indicate data on the digital YUV bus. The positive slope marks the beginning of a
new active line. The HIGH period of HREF is 720 Y samples long. HREF can be used
to synchronize data multiplexer/demultiplexer. HREF is also present during the
vertical blanking interval.
VSSD3
32
P
Ground for digital supply voltage input 3.
VDDD3
33
P
Digital supply voltage 3 (+3.3 V).
VPO
(15 to 10)
34 to 39
O
Digital VPO-bus (Video Port Out) signal; higher bits of the 16-bit VPO-bus or the
16-bit RGB-bus output signal. The output data rate, the format and multiplexing
scheme of the VPO-bus are controlled via I2C-bus bits OFTS0 and OFTS1. If I2C-bus
bit VIPB = 1 the six MSBs of the digitized input signal are connected to these outputs,
congured by the I2C-bus ‘MODE’ bits (see Figs 33 to 40):
LUMA
→ VPO15 to VPO8, CHROMA → VPO7 to VPO0.
VSSD2
40
P
Ground for digital supply voltage input 2.
VDDD2
41
P
Digital supply voltage 2 (+3.3 V).
VPO
(9 to 0)
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-bus bits OFTS0 and OFTS1. If I2C-bus bit VIPB = 1
the digitized input signal are connected to these outputs, congured by the I2C-bus
‘MODE’ bits (see Figs 33 to 40): LUMA
→ VPO15 to VPO8,
CHROMA
→ VPO7 to VPO0.
FEI
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.
GPSW
53
O
General purpose switch output; the state of this signal is set via I2C-bus control and
the levels are TTL compatible.
XTAL
54
O
Second terminal of crystal oscillator; not connected if external clock signal is used.
XTALI
55
I
Input terminal for 24.576 MHz crystal oscillator or connection of external oscillator
with CMOS compatible square wave clock signal.
VSSD1
56
P
Ground for digital supply voltage input 1.
VDDD1
57
P
Digital supply voltage input 1 (+3.3 V).
TRST
58
I
Test reset input not (active LOW), for boundary scan test; notes 1, 2 and 3.
TCK
59
I
Test clock for boundary scan test; note 1.
RTCO
60
O
Real time control output: contains information about actual system clock frequency,
subcarrier frequency and phase and PAL sequence.
