#1C. FifoPiMa V1.5 Master mode Raspberry Pi I2S/DSD/DoP Re-clocker with ultra-low phase noise XOs

Introduction
FifoPi Ma is an audiophile grade Raspberry Pi I2S/DSD/DoP re clocker that works in master clock mode . FifoPiMa successfully achieves an ultra low jitter and ultra low noise performance by using IanCanada's well reputed 1 bit multistage discrete re clock technology . The output signal quality of the FifoPiMa is almost the perfect . It work s great for Paspberry Pi streamer transports ,SYNC mode DACs, external DACs and many other digital audio applications to improv e the sound quality. As a less expensive alternative solution , FifoPi Ma is compatible with FifoPi Q7 in both physical dimensions and electronic connections.

Features and Specifications

• Master clock mode
• Support I2S up to 384KHz
• Support DSD output from DSD64 to DSD 128
• On board DoP decoder enables Raspberry Pi native DSD playback over GPIO
• Two user replaceable socket mounted clocks (XOs or OCXOs, with/without OE pin) support frequencies 22.5792/24.5760 and 45.1584/49.1520 MHz for both 44.1KHz and 48KHz family di gital music. FifoPiMa also works with SinePi to use external high quality sine clocks
• Includes t wo re clock stages to achieve lowest possible jitter performance.
• 1 bit discrete re clock technolog y to ensure so far the best ultra low noise performance as t he same as a ReClockPi. The final I2S/DSD signal quality is almost perfect in terms of the signal integrity.
• Zero delay time
• Two separate DC inputs to provide both clean power to the FiFoPiMa and the optional Raspberry Pi power via GPIO.
• 3.3V ultracapacito r and LifePO4 battery power supplies can be used directly for the FifoPiMa
• Optimized decoupling networks to improve power supply performance more
• AUX GPIO connector is designed to install DAC controllers, MonitorPi or other RPi accessories without affecting the output signal quality.
• Has three o utput groups: U.FL connectors, GPIO and the AUX GPIO . They are all independent from each other.
• To achieve the best possible low jitter performance , high quality U.FL coaxial cable connector s are designed for MCLK and other I2S/DSD outputs in order to runs DACs, digital interface transports in a more professional way.
• Also provides Mute and DSD EN control signals for the following DACs and transport streamers.
• 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)
• With DoP pass through function
• With both continuous and stop clock mode for mute state
• Bit perfect
• Need a standard Linux driver to operate
• Can work with an IsolatorPi to have a galvanic isolation between Raspberry Pi
• Has built in hardware based lossless 16bit to 32bit convertor, works with all kinds of DAC s even they don't support 44.1KHz 16bit music format
• High performance re clock solution fit your budget.
