JESD207 is a Radio Front End – Base Band Digital Parallel (RBDP) interface between a Radio Front-end integrated circuit (RFIC) and a Baseband integrated circuit (BBIC). This IP core together with DDR and PLL functionality integrated in the LatticeECP3™ FPGAs implements baseband (BB) side data and control plane paths. It can be used to connect to a radio front-end (RF) transceiver device with integrated analog to digital converter (ADC) and digital to analog converter (DAC).
The Lattice JESD207 IP core is fully compliant to the JESD207 JEDEC specification.
