The TransportPi Digi is a high performance all-in-one digital audio interface for the Raspberry Pi. It provides ultra-low jitter and low noise signal quality using IAN CANADA's proprietary 3-stage 1-bit discrete reclocking technology for SPDIF signals, and 2-stage multi-bit for I2S signals.
The TransportPi Digi also features two XO / OCXO clock slots for even higher sound quality. Its multitude of outputs (Coaxial, Optical, HDMI, GPIO) makes it a very complete and versatile module.
This product combined with a very good power supply like the UcPI or PurePi makes it one of the best digital interfaces for Raspberry Pi on the market.

This TransportPi Digi is functionally equivalent to an I2S FIFOPI re-clocker + a TransportPi MKII.

Key points:

• 4 high quality reclocked outputs: SPDIF, Optical, I2S, GPIO
• 3-stage discrete 1-bit reclocking for SPDIF signals
• 2-stage multi-bit discrete reclocking for I2S signals
• Pre-installed 45.1584/49.1520 MHz local low noise clocks compatible with FiFoPi
• High quality local MCLK output on U.FL coaxial connector
• Can also operate as an I2S FIFO re-clocker
• Clean low noise 3.3V/5V power input: ideal for working directly with a LifePO4 battery. The built-in LDO can also be bypassed.
• Can share power with the Raspberry Pi
• Works with SinePi to take high quality external sine clocks
• Supports PCM signals up to 192kHz
• Four-layer PCB design with two inner PCB layers as dedicated shielding plates to further reduce noise
• Enhanced power supply filter network with over 130 ultra-low ESR decoupling capacitors
• Uses the standard WM8805 Linux driver
• Bit-perfect and lossless
• Easy-to-use plug-and-play
