Product Features

High quality Audio Sampling Rate Converter board for Raspberry Pi 3B/3B+.

Onboard TI SRC4392 chip accepts I2S signal from Raspberry Pi and converts to accurate S/PDIF output and clean I2S output signal with master clock for DAC. Listen and enjoy jitter-free fine MUSIC.

RAL-SRC4392P provides user-friendly connector layout and mounting holes.

Easy-to-use connector layout provides easy installation into Audio equipment enclosure or stacking on Raspberry Pi 3B.

Three independent S/PDIF output.

RAL-SRC4392P has three different type S/PDIF output. One is coaxial output(RCA Jack) isolated with Digital Isolation trans. Second one is a Optical(Toslink) transmitter. Last one is 3.3V CMOS digital signal and Digital Isolation trans secondary winding for external terminal. AES 3.3V CMOS output is also available at CN4_connector.
