GENERAL DESCRIPTION
The ADV®7330 is a high speed, digital-to-analog encoder on a
single monolithic chip. It includes three high speed video D/A
converters with TTL compatible inputs.
The ADV7330 has separate 8-bit or 16-bit input ports that
accept data in high definition or standard definition video
format. For all standards, external horizontal, vertical, and
blanking signals or EAV/SAV timing codes control the inser-
tion of appropriate synchronization signals into the digital
data stream and therefore the output signal.
Purchase of licensed I2C components of Analog Devices or one of its
sublicensed Associated Companies conveys a license for the purchaser under
the Philips I2C Patent Rights to use these components in an I2C system,
provided that the system conforms to the I2C Standard Specification as
defined by Philips.

NOTES
1Oversampling disabled. Static DAC performance will be improved with increased oversampling ratios.
2DNL measures the deviation of the actual DAC output voltage step from the ideal. For +ve DNL, the actual step value lies above the ideal step value; for –ve DNL,
the actual step value lies below the ideal step value.
3Value in brackets for VDD_IO = 2.375 V to 2.75 V.
4External current required to overdrive internal VREF.
5IDD, the circuit current, is the continuous current required to drive the digital core.
6Guaranteed maximum by characterization.
7IAA is the total current required to supply all DACs including the VREF circuitry and the PLL circuitry.
