Description

The LM1881M Video sync separator extracts timing information including composite and vertical sync, burst/back porch timing, and odd/even field information from standard negative going sync NTSC, PAL*, and SECAM video signals with amplitude from 0.5V to 2V p-p. The integrated circuit is also capable of providing sync separation for non-standard, faster horizontal rate video signals.

Features

1. AC coupled composite input signal

2  > 10 kX input resistance

3. < 10 mA power supply drain current

4. Composite sync and vertical outputs

5. Odd/even field output

6. Burst gate/back porch output

7. Horizontal scan rates to 150 kHz

8. Edge triggered vertical output
