12.1 Specifications
DIGITAL I/O
Number / Type
Eight inputs and eight outputs,
24-bit AES/EBU format, transformer coupled
Channels
16 in/out in single-wire mode, 8 in/out in dual-wire mode
Sample Rates
All standard rates and variable rates up to 192 kHz in both single wire and
dual-wire modes
Sample Rate
Conversion
Sixteen channels available with support for conversion ratios up to 16:1.
Dynamic range: 144 dB. AES16e-SRC model only.
ARCHITECTURE
Core
FPGA-based core contains custom PCI Express interface, data routing and
formatting, device/stream control, digital mixing, clock routing and control,
and DMA engine. 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.
CLOCKING
Sources
Digital inputs 1 – 4, external word-clock on BNC (with optional CBL-
AES1604 cable), internal word-clock on header, on-board low-jitter crystal
oscillator
SynchroLock
Multi-stage, VCXO-based clock generation system with 3000:1 jitter
attenuation. Wide mode tracks off-frequency clocks, narrow mode generates
ultra-low jitter output for standard frequencies.
ON-BOARD DIGITAL MIXER
Type
Hardware-based, low-latency
Routing
Ability to route any input to any or multiple outputs
Mixing
Up to 22 input or playback channels mixed to any output, 40-bit precision
Status
