Features
1 Features
The MC44BS374CA is a Multi-Standard, PAL/NTSC Modulator.
The channel is set by an on-chip high-speed I
2
C compatible bus receiver. A Phase-Locked Loop ( PLL )
tunes the modulator over the full UHF range.
The modulator incorporates a sound subcarrier oscillator and uses a second PLL to derive 4.5, 5.5, 6.0,
and 6.5 MHz subcarrier frequencies. These frequencies are selectable by bus.
The picture-to-sound ratio may be adjusted using the bus. In addition, an on-chip video test pattern
generator can be switched ON with a 1 KHz audio test signal.
The MC44BS374CA also has the following features:
Integrated on-chip programmable UHF oscillator
No external varicaps diodes / inductor or tuned components
Extremely low external components count
Channel 21-69 UHF operation
VHF range possible by internal dividers (30MHz-450MHz)
Boosted TVout level (82 dBuV typical)
High speed read and write I
2
C-bus compatible (800kHz)
I
2
C-bus 5V and 3.3V compatible
Fixed video modulation depth (82% typical)
Peak White Clip disabled by bus
Programmable picture/sound carrier ratio (12dB and 16dB)
Integrated on-chip programmable sound subcarrier oscillator (4.5, 5.5, 6.0 and 6.5 MHz) - No
external varicaps
On-chip video test pattern generator with sound test signal (1kHz)
Low-power programmable modulator standby mode
Transient output inhibit during PLL Lock-up at power-ON
Logical Output Port controlled by bus
ESD protection, minimum 4 kV
