JESD204B

Overview

The JESD204B controller IP is a highly optimized and silicon agnostic implementation of the JEDEC JESD204B.01 serial interface standard targeting both ASICs and FPGAs. The solution by default provides line-speeds of up to 12.5 Gbps per lane while guaranteeing data alignment and synchronization. The standard allows it to optionally by used up to 16 Gbps, but does not recommend running it faster due to the 8b10b encoding.

The core enables quick and reliable deployment of both the transmitter (TX) and the receiver (RX) and comes optionally with a tightly integrated transport layer option, that can dynamically be configured to handle any Multiple-Converter Device Alignment, Multiple Lanes (MCDA-ML) requirements. The IP comes with the widest parameter set available and has gone through extensive testing. The IP core is silicon proven, heavily tested in UVM regression environment and has been interoperability tested with key Data Converter ADC/DAC providers and leading SerDes PHY solutions.

    Unlock your chips full data transfer potential with Interlaken

    WHITEPAPER System and chip designers are challenged like never before. The continuous growth in data consumption is driving demand for higher speeds and capacities, but designs also need to consume less power-per-bit at a lower cost-per-bit. Reliability is, of course, a key requirement, but not at the expense of efficiency and cost. Interlaken provides a high-speed interface with efficiency, reliability and scalability. The design of the Interlaken interface ensures low power consumption and...
