This is a 350-400MHz FSK/ASK receiver that has multichannel, high dynamic range, PLL and VCO integration, image rejection mixer integration, Start Code Detector block (SCD), I2C serial interface, etc.
The STB5701 is a preliminary product in development designed as a multiband FSK/ASK receiver for the 350MHz to 400MHz ISM band. It features an on-chip Phase Locked Loop (PLL), fully integrated VCO, and an Image Rejection Mixer to optimize performance for Set Top Box applications.
The device utilizes BiCMOS SiGe technology in a 5x5mm QFN32L package. Key characteristics include programmable multichannel support, high dynamic range with On-Chip AGC, and a Start Code Detector block controlled via an I2C serial interface.
