12.2 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
Eight channels available with support for conversion ratios up to 16:1.
Dynamic range: 142 dB. Multiple-input SRC phase matching. AES16-SRC
model only.
ARCHITECTURE
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.
CLOCKING
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.
ON-BOARD DIGITAL MIXER
Type
Hardware-based, low-latency
Routing
Ability to route any input to any or multiple outputs
Mixing
Up to four input or playback signals mixed to any output, 40-bit precision
Status
Peak levels to -114 dB on all inputs and outputs.
LSTREAM EXPANSION PORT
Compatibility
Supports Lynx LStream expansion cards including the LS-ADAT 16-
Channel ADAT I/O card
Type
High-speed serial, up to 16 channels @ 24-bits. 14-pin internal connector.
CONNECTIONS
I/O Ports
Two bracket-mounted 26-pin high-density female D-sub connectors. Can be
configured to support eight channel or four channel AES connections.
External Clock
75-ohm BNC word clock input and output provided on XLR breakout cables
Internal Clock
Two 75-ohm board mounted 2-pin headers for word clock input and output
SOFTWARE
