AFE7444 quad-channel RF-sampling AFE with 14-bit 9-GSPS DAC and 3-GSPS ADC evaluation module

Texas Instruments


The AFE7444 evaluation module (EVM) is an RF-sampling transceiver platform that can be configured to support up to four-transmit and four-receive (4T4R) channels simultaneously. The module evaluates the AFE7444 device, which is a quad-channel RF-sampling analog front end (AFE) with 14-bit 9-GSPS digital-to-analog converters (DACs), 14-bit 3-GSPS analog-to-digital converters (ADCs), and on-chip integrated PLL/VCO for high-frequency clock generation for DACs and ADCs.

AFE7444EVM has options to use dual digital up converters and down converters in each channel to synthesize and digitize multiple wideband signals with high dynamic range simultaneously. On-chip integrated digital step attenuator (DSA) for the receiver channels and DSA-equivalent functionality for the transmitter channels are supported. Eight JESD204B-compatible serializer/deserializer (SerDes) transceivers running up to 15 Gbps can be used for providing inputs and outputs to/from the AFE7444 device through the onboard FMC connector.

AFE7444EVM includes the LMK04828 clock generator for providing a reference signal to the AFE on-chip PLL and for generating the required SYSREF signals for the JESD204B protocol. Also included is the option for providing an ultra-low-phase noise external clocking solution.

AFE7444EVM 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 (TSW14J57EVM), as well as many FPGA development kits.
