Device Overview
Figure 2 shows a simplified block diagram of the MC44BC375U/J/Tdevice.
The MC44BC375U/J/T device has two main sections:
1. A modulator section which accepts audio and video inputs and modulates the VHF carrier.
2. A PLL section to synthesize the UHF/VHF output channel frequency (from an integrated
UHF oscillator, divided for VHF output)
The high frequency BICMOS technology permits integration of tank circuit and certain filtering functions.
