| Notes (AES over Fiber): • AES/EBU (AES3) is a digital audio interface; the device transports the AES3 bitstream over optical fiber for long-distance, EMI-immune links. • 110Ω balanced XLR AES3 is commonly used in broadcast and pro-audio for reliable digital audio distribution. • Jitter spec (<0.005 UI p-p) indicates very stable clock/data recovery, important for downstream AES receivers and audio integrity. |
