MC44BS374T1/374T1A Advance Information
Functional Overview
4 Functional Overview
Figure 2 shows a simplified block diagram of the MC44BS374T1/374T1A device.
The MC44BS374T1/374T1A device has three main sections:
1. A high speed I2C-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 MC44BS374T1/374T1A 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.
