The XMOS XTAG-2 is a USB based, ????-channel logic analyzer with up to 50MHz sampling rate.
The XTAG-2 is actually a debug/eval board for XMOS ICs, but it can be used as a logic analyzer with a firmware written by Henk Muller.
See XMOS XTAG-2/Info for more details (such as lsusb -vvv output) about the device.
Hardware¶
The main chip is an XMOS XS1-L1 XS1-L01A-LQ64 Datasheet. In the above picture, the 7-pin header markings are barely unreadable, but that's the jtag port for the xmos chip. From right to left: TDO, TDI, TCK, TMS, TRST#, RST# and GND.
The secondary chip is an SMSC HS Usb 2.0 transceiver.
