Notes
1. Full-scale sinewave (fi = 4.4 MHz; fCLK; fCLK = 27 MHz).
2. The −3 dB bandwidth is determined by the 3 dB reduction in the reconstructed output (full-scale signal at input).
3. The circuit has two clock inputs CLK and CLK. There are four modes of operation:
a) TTL (mode 1); CLK decoupled to DGND by a capacitor. CLK input is TTL threshold voltage of 1.5 V and sampling
on the LOW-to-HIGH transition of the input clock signal.
b) TTL (mode 2); CLK decoupled to DGND by a capacitor. CLK input is TTL threshold voltage of 1.5 V and sampling
on the HIGH-to-LOW transition of the input clock signal.
c) AC drive modes (modes 3 and 4); When driving the CLK input directly and with any AC signal of 0.5 V
(peak-to-peak value) imposed on a DC level of 1.5 V, sampling takes place on the LOW-to-HIGH transition of the
clock signal. When driving the CLK input with such a signal, sampling takes place on the HIGH-to-LOW transition.
d) If one of the clock inputs is not driven, then it is recommended to decouple this input to DGND with a 100 nF
capacitor.
