Data Sheet December 1998 File Number 4106.2
Triple 8-Bit, 50 MSPS, Video A/D Converter with Clamp Function
The HI2303 is a highly integrated 8-bit, 3-channel analog-todigital converter that is designed for component (like RGB) digitizing applications. The internal DC Restore (video clamp) function and voltage reference simplifies system design and saves board space. The HI2303 can digitize RGB, YUV, YIQ and any other analog component color signals used in video systems. The variety of sub-sampling modes is compatible with RGB, YUV and YIQ color systems where 4:4:4, 4:2:2 and 4:1:1 data reduction is needed. The 2-step architecture boasts, low power operation, and excellent video performance.

Description of Operation
TABLE 2. SETTING VALUES AND OUTPUT FORMATS
Digital Output Format
The HI2303 supports eight different output formats as detailed in Table 2. For clarity, these formats are labeled mode 0 to 7. The modes are selected via three control pins labeled CTL0, CTL1 and CTL2. The converter has a latency of five clock cycles which places a constraint on the users ability to change the mode on the fly without corrupting the data within the converter. Please refer to Figure 10. The SY pin is used to control mode changes. This is achieved by using the SY as a reset/latch signal. The Mode is reset when the SY is asserted low. When SY transitions from low to high the control pins are latched internally and mode is changed per timing diagram latency.

HI2303 Mode #6, #7 - Simple Boundary Scan 1 and Scan 2
The HI2303 has a simple boundary scan function.

NOTE: CLK and SY must be set.
Clamp Function
The following two points should be noted when using the digital clamp circuit. - The clamp pulse must be supplied externally. - The clamp circuit is not designed for V cycle clamping.
16 different reference levels can be selected for the digital clamp circuit through a combination of the REF0, REF1, REF2 and REF3 inputs as shown in the table below. Note that the REF0, REF1, REF2 and REF3 input signals are fetched asynchronously with the clock input signal.
A IN ( pedestal ) = V RB + ( Binary Code * LSB ) + E OB
