April 25, 2013 Dual 14-Bit, 250/200/125 MSPS JESD204B High Speed Serial Output ADC
The ISLA224S is a series of low-power, high-performance,
dual-channel 14-bit, analog-to-digital converters. Designed
with FemtoChargeв„ў technology on a standard CMOS process,
the series supports sampling rates of up to 250MSPS. The
ISLA224S is part of a pin-compatible family of 12-and 14-bit
dual-channel A/Ds with maximum sample rates ranging from
125MSPS to 250MSPS and shares the same analog core as
Intersil's proven ISLA224P series of ADCs. The family
minimizes power consumption while providing state-of-the art
dynamic performance, offering an optimal performance-vspower trade-off. Features Differentiating the ISLA224S from the ISLA224P is its highly
configurable, JESD204B-compliant, high speed serial output
link. The link offers data rates up to 4.375Gbps per lane and
multiple packing modes. It can be configured to use two or
three lanes to transmit the conversion data, allowing for
flexibility in the receiver design. The SERDES transmitter also
provides deterministic latency and multi-chip time alignment
support to satisfy an application's complex synchronization
requirements. SPI Programmable Debugging Features and Test Patterns A serial peripheral interface (SPI) port allows for extensive
configurability of the JESD204B transmitter including access …
