Texas Instruments AFE8000EVM Evaluation Module is an RF-sampling transceiver platform that can be configured simultaneously to support up to eight transmit ten-receive (8T10R) channels. The AFE8000EVM evaluates the AFE8000 octal-channel, RF-sampling, analog front ends (AFEs) with 14-bit, 12GSPS digital-to-analog converters (DACs), 14-bit, 4GSPS analog-to-digital converters (ADCs), and an on-chip integrated phased-locked loop/voltage-controlled oscillator (PLL/VCO) for high-frequency clock generation in DACs and ADCs.
The TI AFE8000EVM evaluation module allows the option to use dual digital up and down converters in each channel to simultaneously synthesize and digitize multiple wideband signals with high dynamic range.
An on-chip integrated digital step attenuator (DSA) for the receiver channels and DSA functionality for the transmitter channels are supported on the device. Eight JESD204B/C-compatible serializer/deserializer (SerDes) transceivers running up to 32.5Gbps can furnish inputs and outputs to and from the AFE8000 via the onboard FPGA mezzanine card (FMC) connector.
The AFE8000EVM contains an LMK04828 clock generator for delivering a reference signal to the AFE on-chip PLL and generating the required system reference (SYSREF) signals for the JESD204B/C protocol. Also included is the option for providing an ultra-low-phase noise external clocking solution.
The AFE8000EVM facilitates an efficient power-management solution for the required power rails to the AFE. The design interfaces with the TI pattern/capture card solution (TSW14J58EVM, sold separately) and many FPGA development kits.
