It accepts input sample rates from 4 kHz up to 216 kHz and converts them to a different output rate. ## Sample rate range — what 4 kHz to 216 kHz covers The 4 kHz to 216 kHz span covers low-rate voice codecs up to high-definition audio plus a margin for oversampling. The two channels are independent, so left and right paths can run different rate conversions simultaneously.","metaTitle":"SRC4392IPFB Sample Rate Converter, 4kHz-216kHz, 48-TQFP","metaDescription":"TI SRC4392IPFB sample rate converter, 2-channel, I²C/SPI, 4kHz-216kHz, -40°C to 85°C, 48-TQFP.

Electrical specifications, package (48-TQFP), and temperature range are identical. Choose the Tray version for hand-assembly or low-volume builds; the Tape & Reel variant suits automated pick-and-place lines."},{"question":"Can SRC4392IPFB handle 192 kHz sample rate?","answer":"Yes. The SRC4392IPFB supports input and output sample rates from 4 kHz to 216 kHz, which comfortably covers 192 kHz high-definition audio."},{"question":"Is SRC4392IPFB compatible with I2S and AES3?","answer":"The SRC4392IPFB uses I²C and SPI for control interface. For audio data, it accepts standard digital audio formats including I2S and AES3 (via an external transceiver). The datasheet details the serial audio port configuration."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SRC4392IPFB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SRC4392IPFB when reusing this data.
