IntroductionThe McDualXO is a multi-channel multi-frequency clock board which was designed especially for McFIFO to improve sound quality by utilizing ultra-low jitter technologies. It comes with automatic Fs switching, dedicated low jitter fan-out buffers, ultra-low noise LDO and ultra-high speed re-clocking. Multi-layers PCB design, enhanced power supply design, impedance controlled traces and many other improvements work together to ensure outputting highest quality digital audio clocks and signals. Features and Specifications Has 4 MCLK, 4 SCK, 4 LRCL/D1, 2 SD/D2 and each of D3-D8 signals output, so McDualXO can drive up to 4 mono block/independent DACs at same time. 14 channels for I2S or 8 channels for DSD. All outputs are in U.FL coaxial cable connectors/sockets to optimize for signal integrity. Has 3 dedicated and upgradeable ultra-low noise LDOs for XO, clock fan-out buffer and re-clocking. The 0.9uV RMS, 90dB PSRR, 600mA on-board ADM7154 is especially optimized for OCXO. XO frequency range from 11.2896MHz to 98.3040MHz. XOs with different frequency range can work together at same time. XO can be plugged into any socket without limitation. MCLK * Fs range: 128*Fs, 256*Fs, 512*Fs, 1024*Fs, 2048*Fs, 4096*Fs. Anti-vibration grommet suspension mechanism design for low jitter applications. Can be stacked on top of McFIFO.
