The Noname XL-LOGIC16-100M is a USB-based, 16-channel logic analyzer with up to 100MHz sampling rate.
It is labelled and sold as a Saleae Logic16 clone, and comes with "modified" Saleae Logic software on a CD-ROM. The existing Saleae Logic16 support in libsigrok detects this device as an original, but fails to initialize the FPGA for capture (at the time of writing).
See Noname XL-LOGIC16-100M/Info for more details (such as lsusb -v output) about the device.
Hardware
A single Phillips head screw holds the case together. The parts selection seem to be almost identical to the WayEngineer Saleae16 but that page doesn't have any internal photos for full comparison.
Most notable are the complete lack of test points or programming headers! There are some unpopulated resistor/capacitor pairs on the backside.
- FPGA: Xilinx Spartan-3A XC3S200A, 200K gates (datasheeet)
- USB interface chip: Cypress CY7C68013A-56PVXC (FX2LP) (datasheet)
- I2C EEPROM: 2Kbit Atmel 24C02B (markings: "ATMEL317 24C02BN SU27 D") (datasheet)
- 3.3V voltage regulator: Advanced Monolithic Systems AMS1117-3.3 (datasheet, older datasheet)
- 1.2V voltage regulator: Advanced Monolithic Systems AMS1117-1.2 (datasheet, older datasheet)
- Crystal: 24.000
Three LEDs (USB/green, COM/blue, and RUN/red) are on the board.

Firmware
You can use the sigrok-fwextract-saleae-logic16 tool to extract (from the "Logic" Linux binary) the FX2 firmware and the FPGA bitstreams, exactly as for a real Saleae Logic16. Note, the md5sum of the FX2 firmware is identical to the original Saleae firmware, but the FPGA bitstreams are different. Attempting to connect to this device with the "modified" FPGA bitstream, which _works_ with the vendor supplied "modified" Logic software fails to load in sigrok, with a FPGA version mismatch. The FX2 firmware loads successfully, at least in as much as the LED blinks a heartbeat pattern as expected.
Protocol
Presumably the same as for the Saleae Logic16.
