Preliminary specification
Digital Video Encoders (DENC2-M6)
SAA7184; SAA7185B
Notes to the Characteristics
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 C
L
= 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.
The value is calculated via equation
7.
The value depends on the clock frequency. The numbers given are calculated with f
LLC
= 27 MHz.
8.
The values given are calculated via equation
and
9.
10. For full digital range, without load, V
DDA
= 5.0 V. The typical voltage swing is 2.0 V, the typical minimum output
voltage (digital zero at DAC) is 0.2 V.
The falling edge of DTACK will always occur 1
