Digital To Analog Converters datasheet and documents for ADV7122KSTZ50
Digital To Analog Converters Overview
The ADV7122KSTZ50 is a triple 10-bit video digital-to-analog converter (DAC) operating at 50 MHz. It features three independent pixel input ports for red, green, and blue data, along with composite SYNC and BLANK control inputs. The device utilizes a segmented architecture to ensure monotonicity and low glitch impulse. It accepts TTL-compatible digital inputs and provides high-impedance analog current outputs compatible with RS-343A and RS-170 standards. Powered by a single +5 V supply, it requires an external 1.23 V reference voltage. The component is housed in a 48-lead Thin Quad Flatpack (TQFP) package.
Digital To Analog Converters Feature Summary
- Triple 10-bit DACs with 50 MHz pipelined operation
- Integrated composite SYNC and BLANK control signals
- TTL-compatible digital inputs and RS-343A/RS-170 output compatibility
- Monolithic CMOS construction ensuring guaranteed monotonicity
Digital To Analog Converters Applications
- High Definition Television (HDTV)
- High Resolution Color Graphics
- Video Signal Reconstruction
- Direct Digital Synthesis (DDS)
Digital To Analog Converters Procurement Notes
Verify the speed grade suffix '50' corresponds to the required 50 MHz clock rate. Confirm the 'ST' suffix indicates the 48-lead TQFP package variant. Ensure the K version meets the specified industrial temperature range requirements if applicable beyond the standard 0°C to +70°C range.
Digital To Analog Converters Selection Notes
Select this model when 10-bit resolution and integrated sync controls are necessary. Compare against the ADV7121 if composite sync and blanking inputs are not required. Ensure the system can provide the recommended external 1.23 V reference voltage and appropriate RSET resistor for full-scale current adjustment.
Digital To Analog Converters Part Context
This part belongs to the ADV7121/ADV7122 family of video DACs. The ADV7122 distinguishes itself from the ADV7121 by including dedicated SYNC and BLANK control pins. The KSTZ50 designation specifies the 50 MHz speed grade and the 48-lead TQFP surface-mount package.
Digital To Analog Converters Replacement Considerations
The ADV7121KN50 serves as a functional substitute if composite SYNC and BLANK inputs are not utilized in the design. Other speed grades within the ADV7122 series, such as ADV7122KP80 or ADV7122KP30, offer alternative performance levels but require different packages.
