The HI2301 is an 8-bit CMOS analog-to-digital converter for
video use that features a sync clamp function and on-chip
amplifier. The adoption of a 2-step parallel method realizes
low power consumption and a maximum conversion speed
of 30 MSPS.

CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation
of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.

THE CLAMP INTERVAL
NOTES:
7. The relationship between the CCP voltage (Pin 32) variation and the ADIN voltage variation is positive phase.
8. ∆VADIN/∆VCCP = 3.0 (fS = 20 MSPS).
9. Take care that the phase of ADIN input is inverted against the phase of the digital output, because the use of the built-in inverting amplifier
is standard. (Refer to “Digital Output.”)
