Device Overview
MC44BC373/374 Technical Data
2 Device Overview
Figure 2 shows a simplified block diagram of the MC44BC373/4 device.
The MC44BC373/374 device contains four main sections:
1. A high-speed I2C-compatible bus section.
2. A PLL section — Synthesizes the UHF /VHF output channel frequency (from an integrated
UHF oscillator, divided for VHF output).
3. A modulator section — Accepts audio and video inputs and then uses those inputs to
modulate the UHF/VHF carrier.
4. An Antenna Booster/Splitter — Amplifies and splits the antenna signal into two signals:
a) The modulated signal is added to the amplified antenna signal on the TVOUT pin.
a)
The following items are programmable using the high-speed I2C compatible bus:
Channel frequency
Sound frequency
Sound/picture carrier ratio
An on-chip video test pattern generator with an audio test signal is included.
The MC44BC373 operates as a multi-standard modulator and can handle the following systems using the
same external circuit components:
B/ G
I
D/ K
H
L
M/N
The high frequency BiCMOS technology permits integration of the following functions:
Antenna Booster/Splitter
UHF tank circuit and certain filtering
