The Level Shifter Board, as the name suggests, is designed to shift the voltage level from 1.2V to 3.3V for the Total Phase Aardvark™ I2C/SPI Host Adapter, Beagle I2C/SPI Analyser and Cheetah™ SPI High-Speed Host Adapter.
The Level-Shifter Board allows to your perform level shifting for I2C, SPI, and MDIO signals and supports voltage levels of 1.2V, 1.5V, 1.8V, 2.5V, 3.0V, and 3.3V. It can be used to supply power to downstream devices and transfers I2C signals at a speed of 800 kHz and SPI and MDIO signal at speeds of 20 MHz.
The board has two connectors for connecting to the target interface and two additional connectors to connect an Aardvark™/Cheetah™ Host Adapter and a Beagle™ Protocol Analyser. The board needs to be powered at the Host/Analyser interface by a 5V power supply. This is normally supplied by the Host Adapter or Analyser. The Target interface is powered either from the Target interface itself or from the Host end via a set of jumper selectable voltages.
