MC44CC373
FUNCTIONAL OVERVIEW
Figure 2 shows a simplified block diagram of the
MC44CC373CA and MC44CC374CA modulators.
There are three main sections:
1.
A high speed I2C-compatible bus section for control and
programming.
2.
A PLL section to synthesize the UHF output channel
frequency.
3.
A modulator section, which accepts audio and video
inputs and modulates the RF carrier
An on-chip simple video test pattern generator with an au-
dio test signal is included, but is not shown in the block dia-
gram.
The MC44CC373/4CA operates as a multi-standard mod-
ulator and can handle the following systems using the same
external circuit components: B/G, I, D/K, L, M/N.
The different orderable part numbers provide: a choice in
the pre-programmed power-up default channel frequency,
the output power level and a pre-programmed secondary I2C
address.
