It has three separate, 10-bit, pixel inputs, one each for red, green, and blue video data. A single 5.0V power supply and pixel clock input is all that is required to make the device operational. A bias voltage generator is internal. Each channel clock input can be controlled individually, or connected together as one. The HI2309 also has BLANK video control signal. * Resolution . . . . . . . . . . . . . . . . . . . . . . . . . .

Input data in Figure 10 = all "0" and "1" of rectangular wave, clock frequency = 50MHz for a total value of three channels. time. Set the best values according to the purpose of use. Correlation Between Data and Clock: For HI2309 to display the desired performance as a D/A converter, the data transmitted from outside and the clock must be synchronized properly. Adjust the setup time (tS) and hold time (tH ) as specified in "Electrical Characteristics." VDD , VSS : Separate the analog and digital signals around the device to reduce noise effects. Bypass the VDD pin to each GND with a 0.1F ceramic capacitor as near as possible to the pin for both digital and analog signals. Latch Up: The AVDD and DV DD pins must be able to share the same power supply of the board. This is to prevent latch up caused by potential difference between the two pins when the power is turned on. IREF Pin: The IREF pin is very sensitive to improve the AC Characteristics. Pay attention for capacitance component not to attach to this pin because its output may become unstable. VG Pin: It is recommended to use a 1F capacitor to improve the AC Characteristics, though the typical capacitance value externally connected to the VG Pin is 0.1F. Notes On Operation Selecting the Output Resistance: HI2309 is a current output type D/A converter. To create the output voltage, connect the resistor to the current output pin. Specifications: Output full scale voltage VFS Max = 2.0 [V]. Output full scale current IFS Max = 10 [mA]. Calculate the output resistance from VFS = IFS x R. Connect a resistance sixteen times the output resistance to the reference current pin IREF . In some cases, this value may not exist, a similar value can be used instead. Note that the VFS will be the following: VFS = V REF x 16 R/R'. R is the resistor to be connected to the IO and R' is the resistor to be connected to the IREF . Power consumption can be reduced by increasing the resistance, but this will on the contrary, increase the glitch energy and data setting 10-9 |
