Applications Information
For additional applications information see Applications
Notes available from the factory.
To minimize component count, use of the following on-chip
circuits is recommended:
1.
ADC sampling clock.
2.
Clamp.
3.
Voltage reference
Optimum PLL Conguration Register (address 0x0C)
settings for typical modes are listed in Table 7. Unless
otherwise indicated, all modes are compliant with VESA or
SMPTE specications. For unlisted modes, values should be
adjusted to optimize performance.
By adjusting the values in the gain (GRP, GGY, GBP) and
offset (OSRO, OSGY, OSBP) registers, the input conversion
range can be matched to the incoming analog signals.
AC Coupled Digitizer
Shown in Figure 24 is an implementation of a video digitizer
with AC coupled YPBPRinputs. Horizontal sync input.
Output data is three channel 24-bit pixels with a maximum
rate of 140Ms/s. Data is clocked out on the negative edge of
DCK. HSOUT is delayed HSIN.
Control is through the serial port with 150
resistors
inserted to allow interfacing with 5V logic. If the serial bus is
operates with 3.3V levels, these resistors are unnecessary.
