Intersil Corporation introduced the industry’s fastest, lowest power single and dual channel 14-bit analog-to-digital converters with JESD204B serial outputs. These serial output ADCs provide single channel sampling rates up to 500 Megasamples/ second and dual channel rates up to 250 Megasamples/second.
The ISLA224S/ISLA214S50 series represent the first ADCs now in production with JESD204B serial outputs. The integrated JESD204B-compatible transmitter offers data rates up to 4.375Gbps per lane, requiring only two lanes to support either the dual channel 14-bit 250Msps converter (one lane per channel) or the single channel 14-bit 500Msps device. An optional third lane is included in the transmitter to support the maximum sampling rate while operating the serial lanes at less than 3.125Gbps, providing backwards compatibility with the JESD204A standard to support lower cost FPGAs. The JESD204B transmitter also provides deterministic latency between the ADC sample clock and the serialized data stream. This meets the synchronization requirements of multi-channel and I/Q communications systems. Power consumption for the ISLA224S25 is just 980mW at 250Msps, compared with 1000mW or higher among competitive serial devices with lower sample rates. For the ISLA214S50, power consumption is just 1050mW compared with 2500mW for competing products.
