Kasli is low-cost FPGA carrier, capable of controlling 8 [Eurocard extension modules](Eurocard extension boards). It can act as either an ARTIQ master, or as a slave connected to the master via DRTIO.
Mockup:
Discussion of Kasli specification is Issue #129.
- Compatible with Sinara [EEM standard](Eurocard Extension Modules)
- Hosts 8 EEMs using standard headers
- Backplane connection for 4 extension modules and power?
- Artix, a handful of transcievers, big enough to run a CPU, DRAM controller and a bunch of ARTIQ RTIO PHYs, maybe a 50T in FGG484
- DDR3, SPI flash, a few LEDs, USB FTDI JTAG + UART
- Same clocking/clock recovery/jitter cleaning as Sinara Metlino (SI5324 + oscillator + bootstrap oscillator)
- One SMA connector in the front panel for RTIO reference clock. Input to the SI5324 clock cleaner in stand alone mode or RTIO reference clock output in satellite mode.
- One SMA connector in the front panel to supply the reference clock to the backplane (DDS/VCO reference clock)
- Three SFP cages to the front - provides DRTIO uplink and downlink
- Maybe two SATA to the front or inside
