The circuit has two clock inputs: CLK and CLKN. There are 5 modes of operation:
a) PECL mode 1: (DC levels vary 1:1 with V
b) PECL mode 2: (DC levels vary 1:1 with V
c) PECL mode 3: (DC levels vary 1:1 with V
d) Differential AC driving mode 4: When driving the CLK input directly and with any AC signal of minimum 1 V (p-p) and with a DC level
e) TTL mode 5: CLK input is at TTL level and sampling is taken on the falling edge of the clock input signal. In that case CLKN pin has
Guaranteed by design.
The ADC input range can be adjusted with an external reference connected to pin FSIN. This voltage has to be referenced to V
Output data acquisition: the output data is available after the maximum delay of t
The 3 dB analog bandwidth is determined by the 3 dB reduction in the reconstructed output, the input being a full-scale sine wave.
The total harmonic distortion is obtained with the addition of the first five harmonics.
The signal-to-noise ratio takes into account all harmonics above five and noise up to Nyquist frequency.
Intermodulation measured relative to either tone with analog input frequencies f
amplitude and the total amplitude of both signals provides full-scale to the converter ( 6 dB below full-scale for each input signal). IMD3
is the ratio of the RMS value of either input tone to the RMS value of the worst case third order intermodulation product; IMD2 is the ratio
of the RMS value of either input tone to the RMS value of the worst case second order intermodulation product.

of 2.5 V, the sampling takes place at the falling edge of the clock signal. When driving the CLKN input with the same signal, sampling
takes place at the rising edge of the clock signal. It is recommended to decouple the CLKN or CLK input to DGND via a 100 nF
capacitor.
