The Red Rapids 27x SigStream Series Analog Interface Options / Digital Signal Processing Architectures are assigned a six-digit model number
(Model XXX-YYY) that uniquely identifies the specific hardware features of that unit. The first
three digits are the primary designator used to convey information about the structure of the
analog front-end. The last three digits define the build options to tailor
the product to a specific application.
All of the SigStream primary model number designators define the specific characteristics of the receiver and/or transmitter channels of the
analog front-end. Please note that the actual sample rate is defined by the synthesizer
build option and not necessarily the maximum rate supported by the channel.
There are several build options within each primary designator.
The synthesizer frequency can be set to any value between the minimum and
maximum sample rates supported by the front-end. Fixed frequency synthesizers are
typically used to minimize phase noise, but programmable synthesizers are also
manufactured to cover a range of frequencies. Please note that the Model 276 synthesizer
frequency is set to half the desired sample rate.
The SigStream products are manufactured in three different form factors; PCIe, XMC, and
CCXMC. Although these options are self-explanatory, it is worth noting that some
PCIe products are actually XMC boards mounted to a PCIe/XMC carrier. They behave
the same as a native PCIe product.
All of the SigStream products support AC coupling at the analog RX/TX interface and
most also support DC coupling. The DC coupled option is only necessary when
frequencies below a few hundred kilohertz are important.
Some of the SigStream products have individual coaxial clock and trigger inputs while
others have a single connector that must be configured as one or the other. The CLK/REF option accepts either a 10 MHz reference to phase lock the on-board
frequency synthesizer, or an external sample clock to bypass the synthesizer. The TRIG option accepts either an external trigger to control channel processing or a
1 PPS timing source to synchronize the on-board time of day clock. The coaxial trigger input can be terminated into 50 ohms or a high impedance (HI-Z) buffer.
The GPIO connector receives external triggers that can be used to control channel
processing. The electrical interface supports 3.3 V LVCMOS, 2.5 V LVCMOS, 1.8 V
LVCMOS, or LVDS signaling standards.
Most SigStream products offer digital down converter (DDC) resources to optionally
tune and filter the raw sample data. There are multiple DDC architectures to
address specific application requirements.
The 276-501 Red Rapids Analog Interface Option / Digital Signal Processing Architecture may still be available for purchase and support from Artisan Technology Group beyond End-Of-Life (EOL) by the manufacturer (OEM).
