Preliminary specication
Digital Video Encoder (EURO-DENC)
SAA7182; SAA7183
Notes
1. At maximum supply voltage with highly active input signals.
2. The levels have to be measured with load circuits of 1.2 k
to 3.0 V (standard TTL load) and CL = 25 pF.
3. The data is for both input and output direction.
4. With LLC in input mode. In output mode, with a crystal connected to XTALO/XTALI duty factor is typically 50%.
5. If an internal oscillator is used, crystal deviation of nominal frequency is directly proportional to the deviation of
subcarrier frequency and line/field frequency.
6. For full digital range, without load, VDDA = 5.0 V. The typical voltage swing is 2.0 V, the typical minimum output
voltage (digital zero at DAC) is 0.2 V.
