Si4844-B Functional Block Diagram 4.1. Overview The Si4844-B is the analog-tuned digital-display digital CMOS AM/FM/SW radio receiver IC that integrates the complete receiver function from antenna input to audio output. Working with an external MCU with LCD/LED driver, Si4844-B can output ...
Figure 4. Block diagram of the AM radio receiver A receiver operates by using a radio antenna to detect radio waves; however, this signal is usually relatively weak, therefore an RF amplifier is required to boost the signal so it can be further processed. As the antenna will capture all po...
FIG. 6 is a circuit diagram showing an example of the configuration of a switch-controlled intermediate-frequency amplifier in the same AM radio receiver. FIG. 7 is a block diagram of an AM radio receiver according to Embodiment 2 of the present invention. FIG. 8 is a circuit diagram ...
Si4831/35-B30 Functional Block Diagram 4.1. Overview 4.2. FM Receiver The Si4831/35-B30 is the industry's most advanced fully integrated, mechanical-tuned 100% CMOS AM/FM/SW radio receiver IC. Offering unmatched integration and PCB space savings, the Si4831/35-B30 requires minimum external ...
Functional Block Diagram The Si473x-D60 CMOS AM/FM radio receiver IC integrates the complete tuner function from antenna input to audio output, including a stereo audio AUXIN ADC input for converting analog audio to digital signals. This feature enables a cost-efficient digital audio platform for...
This protocol defines any device that sends data onto the bus as a transmitter, and the receiving device as the receiver. The device that controls the transfer is a master and device being controlled is the slave. The master will always initiate data transfer and provide the clock to transmit...
