Fixed Video Modulation Index
These modulator circuits are intended for use in VCRs, satellite receivers,
set–top boxes, video games, etc. An on–chip high speed I2C compatible bus
receiver is included and is used to set the channel, tuned by a PLL over the
full range in the UHF bands. The modulator incorporates a sound subcarrier
oscillator, using a second PLL to derive 4.5, 5.5, 6.0 and 6.5 MHz carrier
frequencies, selectable by the bus.
For the sound, either frequency modulation with pre–emphasis or
amplitude modulation (MC44353 only) is possible. A control bit (MC44353
only) is used to select AM sound with positive RF modulation (system L). The
level of the sound carrier with respect to the vision carrier and the modulation
depth of both sound and vision may be adjusted by means of the bus. In
addition, an on–chip video test pattern generator may be switched in with a
1.0 kHz audio test signal.
