NOTES

1All measurements are made in 4

× Oversampling Mode unless otherwise speciﬁed and are guaranteed by characterization. For 2 × Oversampling Mode, the power

requirements for the ADV7194 are typically 3.0 V.

2Temperature range T

MIN to TMAX: 0

°C to 70°C.

3For all inputs but PAL_NTSC and ALSB.

4For PAL_NTSC and ALSB inputs.

5For all outputs but

VSO/TTX/CLAMP.

6For

VSO/TTX/CLAMP outputs.

7Measurement made in 2

× Oversampling Mode.

8I

DAC is the total current required to supply all DACs including the V REF circuitry.

9All six DACs on.

10I

CCT or the circuit current, is the continuous current required to drive the digital core without I PLL.

Speciﬁcations subject to change without notice.

(VAA = 3.0 V, VREF = 1.235 V, RSET1,2 = 1200

unless otherwise noted. All speciﬁcations TMIN to TMAX

2

unless otherwise noted.)
