Description
8-Bit Pixel Port (P7 to P0). P0 is the LSB. Refer to Table 30 for input
modes (ADV7390/ADV7391).
16-Bit Pixel Port (P15 to P0). P0 is the LSB. Refer to Table 31 for input
modes (ADV7392/ADV7393).
Pixel Clock Input for HD (74.25 MHz), ED
SD (27 MHz).
Horizontal Synchronization Signal. This pin can also be configured to
output an SD, ED, or HD horizontal synchronization signal. See the
External Horizontal and Vertical Synchronization Control section.
Vertical Synchronization Signal. This pin can also be configured to
output an SD, ED, or HD vertical synchronization signal. See the
External Horizontal and Vertical Synchronization Control section.
Multifunctional Pin: Subcarrier Frequency Lock (SFL) Input/SPI Data
Output (MISO). The SFL input is used to drive the color subcarrier
DDS system, timing reset, or subcarrier reset.
Controls the amplitudes of the DAC 1, DAC 2, and DAC 3 outputs. For
full-drive operation (for example, into a 37.5 Ω load), a 510 Ω resistor
must be connected from R
example, into a 300 Ω load), a 4.12 kΩ resistor must be connected
from R
Compensation Pin. Connect a 2.2 nF capacitor from COMP to V
DAC Outputs. Full-drive and low-drive capable DACs.
Multifunctional Pin: I
Multifunctional Pin: I
Multifunctional Pin: ALSB sets up the LSB
address/SPI slave select (SPI_SS).
Resets the on-chip timing generator and sets the ADV739x into its
default mode.
Analog Power Supply (3.3 V).
Digital Power Supply (1.8 V). For dual-supply configurations, V
be connected to other 1.8 V supplies through a ferrite bead or
suitable filtering.
Input/Output Digital Power Supply (3.3 V).
PLL Power Supply (1.8 V). For dual-supply configurations, PV
be connected to other 1.8 V supplies through a ferrite bead or
suitable filtering.
