MC44BS374CA Functional Overview
4 MC44BS374CA Functional Overview
Figure 2 shows a simplified block diagram of the MC44BS374CA device.
The MC44BS374CA device has three main sections:
1. A high speed I
2
C-compatible bus section
2. A PLL section to synthesize the UHF / VHF output channel frequency (from an integrated
UHF oscillator, divided for VHF output)
3. A modulator section, which accepts audio and video inputs, then uses them to modulate the
UHF/VHF carrier
An on-chip video test pattern generator with an audio test signal is included.
The MC44BS374CA operates as a multi-standard modulator and can handle the following systems using
the same external circuit components: B / G, I, D / K, M / N.
High frequency BiCMOS technology allows integration of the UHF tank circuit and certain filtering
functions.
