A
RCHITECTURE
Core
FPGA-based core contains custom PCI interface, data routing and
formatting, device/stream control, digital mixing, clock routing and control,
and DMA engine. 256 Kbytes of on-board RAM for data buffering.
Support for field upgrades of firmware.
Audio Devices
Card is visible to host applications as eight record devices and eight play
devices. Each device has two channels and can be used independently for
multi-client functionality.
C
LOCKING
Sources
Digital inputs 1 – 4, external word clock (XLR model only) on BNC, internal
word clock on header, on-board low-jitter crystal oscillator
SynchroLock
Multi-stage, VCXO-based clock generation system with high jitter
attenuation. Wide mode tracks off-frequency clocks, narrow mode generates
ultra-low jitter output for standard frequencies.
