Note 1:
“Absolute Maximum Ratings” are those parameter values beyond which the life and operation of the device cannot be guaranteed. The stating herein of
these maximums shall not be construed to imply that the device can or should be operated at or beyond these values. The table of “Electrical Characteristics” speci-
fies acceptable device operating conditions.
Note 2:
Current flow into device pins is defined as positive. Current flow out of device pins is defined as negative. All voltages are stated referenced to V
SS
= 0V.
Note 3:
Typical values are stated for V
DD
= +5.0V (CLC021VGZ-5.0) or +3.3V (CLC021VGZ-3.3) and T
A
= +25C.

CLK
= 27 MHz derived from Tektronix TG2000 black-burst
reference. Timing jitter measured with Tektronix VM700T using jitter measurement FFT mode, frame rate, 1 kHz filter bandwidth, Hanning window.
Note 7:
