New JESD204A Solutions VideoAs demand for data has increased, higher bandwidth analog-to-digital (ADC) and digital-to-analog (DAC) converters have become necessary to meet the system performance requirements. These devices can be found in many applications, including wireless base station receivers, power amplifier linearization, multi-carrier multi-mode receivers, high interface sampling receivers, radar systems, test and measurement equipment, medical equipment, etc.
JESD204A describes a serialized interface between data converters and logic devices. While the JESD204 spec supports single-lane links, the JESD204A spec improves on that with support for multiple data converter channels or lanes to be bonded synchronously.
NXP Semiconductors has developed two low-cost converter boards with the LatticeECP3 FPGA family using the Lattice JESD204A IP Core. The NXP DAC1408 is a 14-bit JESD204A digital-to-analog converter. The NXP ADC1413 is a 14-bit JESD204A analog-to-digital converter. Please contact NXP for more information on these boards.

The LatticeECP3 FPGA family offers multi-protocol 3.2G SERDES, DDR/DDR2/DDR3 memory interfaces, powerful DSP capabilities, high density on-chip memory and up to 149K LUTS.
The Lattice JESD204A IP core supports both a receive (Rx) core (ADC-to-FPGA direction) and/or a transmit (Tx) core (FPGA-to-DAC direction). The Rx and Tx cores can each be generated separately and with different parameters.
