Description
KT0626M is one of product series of revolutionary wireless microphone chip family-KT06xx. Compared to the traditional solution, this product solution can save hundreds of electronic devices and also maintain a high level of sound quality and functionality.
KT0626M is a UHF wireless transmitter chip, internally integrated with audio amplifier, pre-emphasis filter, companding circuit and phase-locked loop frequency synthesizer, configurable power amplifier. It uses frequency modulation to demodulate the audio signal transmitted by KT0626M, and the working band is in the UHF frequency band.
KT0626M only needs a low-voltage power supply because of its built-in voltage regulator. Using KT0626M to design products can avoid tedious external debugging and save a lot of development investment.
KT0626M supports the function of digital auxiliary channel.
KT0626M can support 2-wire slave mode, which can be configured through MCU . It is a small size package 24-pin QFN.
