TTL
A/D Converter Clock Output.
Generated by an internal phase-
locked loop slaved to VGAHS.
Internal ADCLK divided by N Output.
Enabled by A
0
and A
1
pins
according to Table 1 or by VGA Control Register 1.
A/D PLL Loop Filter Connection.
An external RC network is
connected here.
Encoder Clock Output.
Generated by an internal phase-locked loop
slaved to VGAHS.
Internal PXCK divided by M Output.
Enabled by A
0
and A
1
pins
according to Table 1 or by VGA Control Register 1.
Encoder PLL Loop Filter Connection.
An external RC network is
connected here.
Subcarrier Reference Crystal/Clock.
Connection terminals for an
external 27 MHz crystal. Alternatively, the XTAL
1
pin may be used as
an input from an external oscillator or clock. Subcarrier frequency
accuracy is based on this clock.
Subcarrier Reference Clock Output.
Buffered TTL output from
27MHz crystal oscillator/reference clock.
VGA Horizontal Sync.
Incoming VGA sync may be of either polarity
(active LOW or active HIGH). VGAHS frequency must be within 2%
of the nominal specified value. The VGAHS pin has a light pull-up and
a Schmitt trigger.
