Test Conditions
1. The supply current with no input signal
2. The pin output voltage (the center bias voltage) with no input signal
3. Measure the C-OUT output when a 350-mVp-p sine wave is input to C-IN1 and C-IN2.
4. Measure the comb depth from the C-OUT output when a 350-mVp-p sine wave with frequency fa is input to C-IN1
5. Measure the C-OUT output when a 200-mVp-p sine wave is input to C-IN1 and C-IN2, and when a 500-mVp-p sine
6. Measure the 4fsc (14.3 MHz) and fsc (3.58 MHz) components in the C-OUT output with no input signal.
7. Measure the noise in the C-OUT output with no input signal.
8. Input a 350-mVp-p sine wave to C-IN1 and C-IN2. Let V1 be the C-OUT output when SW3 is set to the ‘a’ position,
9. The delay time in the C-OUT output with respect to the C-IN1 input. This is the CCD 1.5-bit delay.
10. The pin output voltage (clamp voltage) with no input signal.
