MC44BS373CA Functional Overview
4 MC44BS373CA Functional Overview
Figure 2 shows a simplified block diagram of the MC44BS373CA.
Figure 2. MC44BS373CA Simplified Block Diagram
The MC44BS373CA device has three main sections:
A high-speed I2C-compatible bus section
A PLL section to synthesize the UHF /VHF output channel frequency (from an integrated UHF
oscillator, divided for VHF output)
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 MC44BS373CA operates as a multi-standard modulator and can handle the following systems using
the same external circuit components: B /G, I, D /K, L, M/N.
High-frequency BiCMOS technology allows integration of the UHF tank circuit and certain filtering
functions.
