• Manufacturer Part Number: SAA7124WP
• Description: Digital Video Encoder ECO-DENC
• Manufacturer: PHILIPS [NXP Semiconductors]

Philips Semiconductors
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 C
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
6. For full digital range, without load, V
