The RockyLogic Ant8 is an 8-channel, 500MHz logic analyzer.
See RockyLogic_Ant8/Info for more details (such as lsusb -vvv output) about the device.
Components
- Xilinx Spartan-II XC2S30 VQ100AMS0341 (FPGA; 13,824 total distributed RAM bits, 24K total block RAM)
- Xilinx XC9572XL VQ44BMN0345 10C (CPLD; 10ns pin-to-pin logic delays)
- FTDI FT245BM (USB FIFO device)
- IDT ICS501M (clock multiplier)
- Atmel AT93C66 (4kB, three-wire serial EEPROM)
- ON Semiconductor (On) HC00A PGZI (quad 2-input NAND gate)
- National/TI LP2989 (marking: 33AB 2989 IM-2.5) (micropower/low-noise, 500mA ultra low-dropout regulator)
- 20MHz crystal (for the FPGA)

Status
Support for this device is currently being worked on.
Protocol
See the Ant18e wiki page for a description of the Ant8/Ant16/Ant18e protocol.
DIY Ant8 probe cable
The Ant8 cable shipped with the device doesn't have the best quality probes/hooks, but you can easily make your own cable where you can attach the better-quality E-Z Hooks.
Requirements:
- 10-pin colored ribbon cable, such as this one.
- The colors match the one shipped with the Ant8 (white, gray, purple, blue, green, yellow, orange, red, brown) if you remove the 10th (black) lead. The brown lead is GND.
- A "SUB-D" connector where you can attach the ribbon cable, such as this one.
- 5 female-female jumper wires, such as these ones, which we'll cut into two halves to get 10 female connectors (only 9 needed).
- 9 short pieces of heat-shrink tubing.
- 9 E-Z Hook grippers/hooks to attach to the cable.
