Advance Information
PLL Tuned UHF Audio/Video
Modulator ICs for PAL, SECAM
and NTSC TV Systems
MC44353 – Multi–Standard Modulator IC
MC44354 – PAL/NTSC Modulator IC
MC44355 – PAL/NTSC Modulator IC with
MC44355 –
set–top boxes, video games, etc. An on–chip high speed I 2 C 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.
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.
