AFE7950EVM

The AFE7950 evaluation module (EVM) is an RF-sampling transceiver platform that can be configured to simultaneously support up to four-transmit and six-receive (4T6R) channels. The module evaluates the AFE7950, which is a quad-channel, RF-sampling, analog front end (AFE) with 14-bit, 12-GSPS, digital-to-analog converters (DACs), 14-bit, 3-GSPS, analog-to-digital converters (ADCs), and on-chip integrated phase-locked loop/voltage-controlled oscillator (PLL/VCO) for high-frequency clock generation for DACs and ADCs.

AFE7950EVM has options to use dual digital up converters and down converters in each channel to simultaneously synthesize and digitize multiple wideband signals with high dynamic range. On-chip integrated digital step attenuator (DSA) for the receiver channels and DSA functionality for the transmitter channels is supported.

Eight JESD204B/C-compatible serializer/deserializer (SerDes) transceivers running up to 29.5 Gbps can be used for providing inputs and outputs to/from AFE7950 through the onboard FPGA mezzanine card (FMC) connector. AFE7950EVM includes the LMK04828 clock generator that provides a reference signal to the AFE on-chip PLL and generates the required SYSREF signals for the JESD204B/C protocol. Also included is the option for providing an ultra-low-phase noise external clocking solution.

AFE7950EVM implements an efficient low-dropout (LDO)-less power-management solution using only DC-DC converters for the required power rails.

The design interfaces with the TI pattern/capture card solution (TSW14J56EVM, sold separately), as well as many FPGA development kits.
