EVM Description

The AFE722x EVM includes a great level of flexibility to enable the user to test it in a more system like

environment. The individual power rails can be generated through LDOs or DC/DC converters from a 6 V

power source and the EVM clock architecture allows for external clock input as well as clock generation

using a low jitter PLL in combination with a VCXO. On the transmit side the EVM provides the option of

connecting directly to the DAC outputs or perform up-conversion via on board IQ modulator.

On the digital side the EVM provides a seamless interface to the TSW1200 capture card in order to

evaluate received data directly on a PC. The TSW3100 pattern generation card can be used to provide

data to the dual DAC of the AFE722x and the on board CDCE72010 generates the appropriate clock for

the TSW3100 for synchronous operation. Both AFE722x and CDCE72010 can be programmed via SPI

conveniently through the USB connection.
