Description
SN11300
SONiX
SN11300 is a highly integrated single chip USB audio controller that suitable
for VoIP USB phone applications. It includes USB1.1 audio control, a 16-bit multi-bit
sigma-delta mono audio CODEC, an 8-bit MCU, PLL, regulator. It has maximum 16
GPIO pins can constitute a 64 key matrix directly support keypad control function.
It’s also support buzzer output pin and LCM for VoIP application. It supports 8 to 48
KHz sampling rates in analog playback and recording via EEPORM setting. Moreover,
SN11300 provided two series bus interface with external MCU application for
advanced functions. With so many features and low-lost cost, SN11300 is an ideal
chip to build a USB VoIP phone solution.
