AES3-2003, AES11-2003 and IEC958 SPDIF DESCRIPTION The ATI Model MCDA-208 contains an ultra-low jitter studio master clock generator, dual 1X4 AES/EBU Digital Audio Distribution. Operation of the unit is simple and straightforward, and it is housed in a rugged 2U rack mount enclosure. All audio connections are made directly to the unit’s built-in BNC connectors, and no special breakout cables or accessory jack panels are... - Page 5 Since the purity of the clock reference is critical to the quality of the finished audio product, ATI has taken steps to assure that the MCDA generates the lowest jitter clock reference available. The MCDA’s internal reference is derived from a 24 MHz precision oscillator and divided down to achieve an ultra-stable signal, rather than multiplying up from a base reference as in some other units.
