I see that several Analog Devices ADCs have an LVDS (high-speed serial) output. Do any Analog Devices DSPs have an LVDS input? Is there any way to route the LVDS sample stream from an ADI ADC into an ADI DSP?
from TigerSharc datasheet:
The processor’s two full-duplex link ports each provide additional
four-bit receive and four-bit transmit I/O capability,
using low-voltage, differential-signal (LVDS) technology. With
the ability to operate at a double data rate—latching data on
both the rising and falling edges of the clock—running at
250 MHz, each link port can support up to 250M bytes per second
per direction, for a combined maximum throughput of
1G byte per second.
I don't know of any ADI DSPs with LVDS inputs. Certainly none of the SHARCs have this feature.
We use LVDS routinely with SPORTs. You will probably need a Quad Receiver. There are several choices. The SN65LVDS390D is my favorite since the inputs are on one side of the device and the outputs on the other. This makes for the easiest PCB routing
If you are routing a low jitter clock, a single SN65LVDS2 might be useful so that you don't introduce jitter from other channels.
Look up TigerSharc, they have LVDS lines
