23020010 819.200KHZ
CRYSTAL 819.200KHZ - 819.200 kHz is most often associated with microprocessor and peripheral applications, not broadcasting or radio communication. The frequency is created by crystal oscillators and used as a precise clock signal in electronic devices, such as: Computer components: Microprocessors, peripherals, and other digital integrated circuits often use a crystal oscillator to provide a stable, accurate timing signal for internal operations.
Audio and digital-to-analog conversion (DAC): Some sigma-delta modulators and other audio components use an 819.2 kHz clock frequency for precise signal sampling.
Specialized equipment: The frequency has been referenced in relation to cable identification instruments, where it is a maximum signal sampling rate.
Radio development (as an intermediate frequency): While not a broadcast frequency itself, 819.2 kHz has been considered in hobbyist radio experiments for creating a precise AM carrier signal through division of a higher frequency. It's important to distinguish between this and broadcast radio. The 819.2 kHz frequency falls within the AM broadcast band, which in North America runs from 535 kHz to 1705 kHz. However, no major radio stations broadcast on this exact frequency. Instead, it is a highly specific value used internally in electronics
