Avnera Corporation Samsung Module Manual 1. Introduction This features is a highly integrated, single-chip, wireless audio solution. This integrates the following: a complete 2.4 GHz RF transceiver, the VMI™ wireless communication system PHY & MAC, advanced power management, audio DSP, I2S interfaces and a full complement of programmable digital interfaces to support a wide range of end-product user communication requirements. 2. Hardware Architecture: 2.
Avnera Corporation Samsung Module Manual - Time base of the RF frequency For Zero IF and RF frequency, a crystal (16MHz) is a clock reference. - Synthesizer Synthesizer inside transceiver internal voltage controlled oscillator (VCO) provides the desired LO Signal base on the phase-locked loop (PLL) with a relatively wide tuning range for this application. - Transmission In transmit mode, the audio engine controlled I2S, transforms the audio data into packetized digital IQ signals.
