AFE707xEVM Evaluation Module
This is the user’s guide for the AFE707xEVM evaluation module (EVM). The AFE7070/71 is a dual 14-bit
65-MSPS digital-to-analog converter with an integrated quadrature modulator. The NCO and LVDS output
functions are not available with the AFE7071 but the AFE7070 has both functions. This is the sole
difference between the AFE7070 and the AFE7071. Hereafter, the AFE707x is referred to as AFE7070.
The EVM also includes the CDCM7005 clock synchronizer, which provides the necessary clocks for the
AFE and pattern generator. This EVM is ideally suited for mating with the TSW1400 pattern generation
card for evaluating WCDMA, LTE, or other high-performance modulation schemes.
