The Sysclk AX-Pro is a USB-based, 8-channel logic analyzer with up to 24MHz sampling rate, and with 2 additional analog channels.
It is a clone of the CWAV USBee AX-Pro.
In sigrok, we use the open-source fx2lafw firmware for this logic analyzer.
See Sysclk AX-Pro/Info for some more details (such as lsusb -v output) on the device.
Hardware
- Main chip: Cypress CY7C68013A-56LTXC (FX2LP)
- I2C EEPROM: Atmel ATML125 24C02N SU27 D
- Auxiliary 8051 chip: STC STC15F104E (purpose is unknown)
- Supply voltage regulator: Advanced Monolithic Systems AMS1117-3.3
- Reference voltage regulator: Advanced Monolithic Systems AMS1117-2.851218
- Analog-to-Digital converter: Texas Instruments TLC5510I
- Analog input amplifiers: Analog Devices AD8065 (SMD marking "HRA")
- Analog amplifiers negative supply: Texas Instruments LMC7660
- Some operational amplifiers: Texas Instruments LM358
- Analog channel switching relay: TQ2-2V
- Crystal: 24MHz
The analog channels are multiplexed by relay or solid-state IC to one ADC.

Protocol
Since we use the open-source fx2lafw firmware for this device, we don't need to know the protocol.
