The Ian Canada FifoPiMa is an audiophile I2S/DSD/DoP reclocker for the Raspberry Pi running in Master Clock mode. Its functionality is equivalent to that of a FifoPiQ3 combined with a ReclockPi. Moreover, the FifoPiMa ensures ultra-low jitter and noise, thanks to the use of the brand's 1-bit multi-stage discrete reclocking technology. The output signal quality of the FifoPiMa is almost perfect. The module works perfectly for Raspberry Pi based streamers, for DACs in SYNC mode or even for external DACs to improve their audio quality. It is also compatible with the FifoPi Q3.

This IAN CANADA FIFOPI module can work with the Hifiberry DAC+ PRO driver under any Raspberry Pi solution.

Key features :

• Master Clock mode.
• I2S support up to 384kHz.
• DSD support from DSD64 to DSD128.
• Integrated DoP decoder for playback of native DSD streams on Raspberry Pi via GPIO.
• Two replaceable bracket-mounted clocks, supporting 22.5792/24.5760MHz and 45.1584.49.1520MHz frequencies. The FifoPiMa also works with the SinePi, allowing the use of high quality external sine clocks.
• Incorporates two reclocking stages to achieve the lowest possible jitter.
• 1bit discrete reclocking technology ensures the best possible performance in terms of noise. The final I2S/DSD signal quality is almost perfect in terms of integrity.
• Zero delay.
• Two separate DC inputs to provide clean power supply to FifoPiMa and Raspberry Pi via GPIO.
• A LifePO4 battery power supply and 3.3V supercapacitors can be used directly with the FifoPiMa.
• Optimized decoupling network to improve power supply performance.
• AUX GPIO connector designed to install DAC controllers, MonitorPi or any other Raspberry Pi accessory, without affecting the output signal quality.
• Three output groups: U.FL, GPIO and AUX GPIO connectors. Each output is independent of the others.
• In order to obtain the lowest possible jitter, U.FL cables and connectors are used.
• Provides Mute and DSD EN control signals for DAC and streamer.
• MCLK Jitter = square (XO jitter^2 + 18fs^2) @ (12kHz-20MHz)
• I2S/DSD signals jitter = square (XO jitter^2 + 18fs^2 + flip-flop additive jitter^2) @ (12kHz-20MHz)
• DoP Pass Through function.
• Bit-perfect.
• Standard Linux driver needed to work.
• Can be used with an IsolatorPi to provide galvanic isolation between the FifoPiMa and the Raspberry Pi.
