Ian Canada's TransportPi AES is an AES/EBU and SPDIF digital interface board. It is the first model to use a 1bit 50Mbps differential driver and a dedicated femtosecond clock to achieve the highest possible signal quality and very low noise for both AES/EBU and SPDIF outputs. The module also incorporates an excellent 1bit discrete reclocker, similar to the ReClockPi, to provide extremely low jitter. The TransportPi AES is thus positioned as a true flagship in the field of audiophile AES/EBU and SPDIF interfaces, allowing a significant improvement in the sound quality of an external DAC.

Key features :

• High-end AES/EBU and SPDIF interface module with isolated AES/EBU, coaxial and Toslink optical outputs (BNC output not isolated).
• 1bit 50Mbps discrete differential driver to achieve the best possible AES/EBU signal quality with very low noise.
• Dedicated femtosecond clock for SPDIF outputs to achieve the best possible signal quality and extremely low jitter.
• Integrated 3-stage 1bit discrete secondary reclockers.
• Improved high bandwidth power supply filtering networks.
• LDO-free architecture for direct use of a 3.3V supercapacitor or battery power supply to get the best power supply performance.
• Optimized PCB impedance control for high speed AES/EBU and SPDIF signals
• 4-layer PCB with dedicated shielding layer to eliminate EMI noise.
• Ultra-low noise metal film resistors to ensure the lowest possible noise level.
• Support of AES/EBU and SPDIF streams up to 192kHz. Possibility to support 384kHz with qualified receiver.
• Interchangeable and upgradeable AES/EBU and SPDIF transformers
• Support for MCLK frequencies from 5.6448MHz to 98.304MHz.
• Support of I2S and DoP formats in input.
