The ChronoVu LA16 is a USB-based 16-channel logic analyzer with up to 200MHz sampling rate.

It features a Xilinx FPGA for sampling, 8MByte of built-in SDRAM to store the samples, and can trigger on low/high/any state or rising/falling/any edge of any combination of probes. After the 8MByte sample buffer is full, the data is transferred to the host via an FTDI FT245RL chip.

See ChronoVu LA16/Info for more details (such as lsusb -vvv output) about the device.

Many thanks to the vendor (ChronoVu) for freely providing information on the protocol used to communicate with the device. This helped us implement the libsigrok hardware driver more quickly. We're happy to see more open-source friendly vendors support sigrok!
