TERMINAL
I/O
DESCRIPTION
NAME
NO.
SYSHS,
SYSVS
121, 122
I
System horizontal and vertical sync inputs. These signals should be selected for
all modes other than VGA mode 2. These signals are pipeline delayed and each
may be inverted before being passed to the HSYNCOUT and VSYNCOUT
terminals. General control register bits GCR(1,0) control the polarity inversion.
If used to generate the sync level on the green current output, SYSHS and
SYSVS must be active low at the input to the TVP3030.
VGABL
126
I
VGA blank input. VGABL is active low. This should be selected when in VGA
mode 2 (CLK0 latching of VGA data and video controls). VGABL is pipeline
delayed before being passed to the DACs.
VGAHS,
VGAVS
124, 125
I
VGA horizontal and vertical sync inputs. These signals should be used when in
VGA mode 2 (CLK0 latching of VGA data and video controls). These signals are
pipeline delyed and each may be inverted before being passed to the
HSYNCOUT and VSYNCOUT terminals. General control regiser bits GCR(1,0)
control the polarity inversion. If used to generate the sync level on the green
current output, VGAHS and VGAVS must be active low at the input to the
TVP3030.
VGA7–VGA0
112–119
I
VGA port. This bus can be selected as the pixel input bus for VGA modes, but
it does not allow for any multiplexing.
WR
65
I
Write strobe input. A logic 0 on this terminal initiates a write to the register map.
Write transfer data is latched from the D(7–0) bus with the rising edge of WR.
XTAL1,
XTAL2
155, 156
I/O
Connection for quartz crystal resonator as a reference for the frequency
synthesis PLLs. XTAL2 may be used as a TTL reference clock input, in which
case XTAL1 is left unconnected.
NOTE: All unused inputs should be tied to a logic level and not be allowed to float.
