ADVANCE INFORMATION

Micronas
Pin 37, 38, 39
Analog RGB Outputs,
ROUT, GOUT,
BOUT
(Fig. 3
–
12)
This are the analog Red/Green/Blue outputs of the
backend. The outputs sink a current of max. 8 mA.
Pin 40
DAC Reference Decoupling,
VRD
(Fig. 3
–
20)
Via this pin the DAC reference voltage is decoupled by
an external capacitance. The DAC output currents
depend on this voltage, therefore a pull-down transis-
tor can be used to shut off all beam currents. A decou-
pling capacitor of 3.3
μ
F/100 nF is required.
Pin 41, 42, 43, 45, 46, 47
Analog RGB Inputs,
RIN1/
2, GIN1/2, BIN1/2
(Fig. 3
–
11)
These pins are used to insert an external analog RGB
signal, e.g. from a SCART connector which can by
switched to the analog RGB outputs with the fast blank
signal. The analog backend provides separate bright-
ness and contrast settings for the external analog RGB
signals.
Pin 44, 48
Fast Blank Inputs,
FBLIN1/2
(Fig. 3
–
15)
These pins are used to switch the RGB outputs to the
external analog RGB inputs.
Pin 49
Main Clock Output,
CLK20
( Fig. 3
–
6)
This is the 20.25 MHz main system clock, that is used
by all circuits in a high-end VDP system. All external
timing is derived from this clock.
Pin 50
Horizontal Drive Output,
HOUT
(Fig. 3
–
13)
This open drain output supplies the the drive pulse for
the horizontal output stage. The polarity and gating
with the flyback pulse are selectable by software.
Pin 51, 52
Crystal Input and Output,
XTAL1
,
XTAL2
(Fig. 3
–
5)
These pins are connected to an 20.25 MHz crystal
oscillator is digitally tuned by integrated shunt capaci-
tances. The Clk20 signal is derived from this oscillator.
Pin 53, 54, 60
Analog Chroma Inputs,
CIN1, CIN2/
CRIN, CBIN
,
(Fig. 3
–
7, Fig. 3
–
8)
CIN1, CIN2 are the analog chroma inputs for S-VHS. A
S-VHS chroma signal is converted using the chroma
(Video2) AD converter. A resistive devider is used to
BIAS the inout signal to middle of converter range. The
input signal must be AC coupled. Together with the
CBIN pin CIN2 can alternatively be used as chroma
component input for the analog YC
R
C
B
interface.
Pin 55
Ground (Analog Front-end),
GNDAF
Pin 56
Ground (Analog Signal Input),
SGND
(Fig. 3
–
10)
This is the high quality ground reference for the video
input signals.
Pin 57
Reference Voltage Top,
VRT
(Fig. 3
–
10)
Via this pin, the reference voltage for the A/D convert-
ers is decoupled. The pin is connected with 10
μ
F/
47 nF to the Signal Ground Pin.
Pin 58
Supply Voltage (Analog Front-end),
VSUPAF
Pin 59
Analog Video Output,
VOUT
(Fig. 3
–
9)
The analog video signal that is selected for the main
(luma, cvbs) adc is output at this pin. An emitter fol-
lower is required at this pin.
Pin 61...64
Analog Video Input 1
4,
VIN1
4
(Fig. 3
–
7)
These are the analog video inputs. A CVBS or S-VHS
luma signal is converted using the luma (Video 1) AD
converter. The input signal must be AC-coupled.
