Min Voltage (typical range): 12 V
Length: 26.075 mm
Description
The LM1886 is a TV video matrix D to A converter which encodes luminance and color difference signals from 3-bit red green and blue inputs The luminance output is encoded from the NTSC equation Y e 0 3R a 0 59G a 0 11B and the R-Y and B-Y outputs are weighted to prevent overmodulation A built-in R-Y and burst gate polarity switch allow European PAL compatible signals to be encoded All output levels including an RF O Carrier Bias Voltage have been referenced to 5V for direct connection to the LM1889 TV video modulator When used in combination with the LM1889 and a suitable sync generator 3-bit R G and B information may be encoded to both composite video and RF channel carrier.
