The ISLA224S is a series of low-power, high-performance,
dual-channel 14-bit, analog-to-digital converters. Designed
with FemtoCharge™ 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.
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.
A serial peripheral interface (SPI) port allows for extensive
configurability of the JESD204B transmitter including access
to its built-in link and transport-layer test patterns. The SPI port
also provides control for numerous additional features
including the fine gain and offset adjustments of the two ADC
cores as well as the programmable clock divider, enabling 2x
and 4x harmonic clocking.
The ISLA224S is available in a space-saving 7mmx7mm 48 Ld
QFN package. The package features a thermal pad for
improved thermal performance and is specified over the full
industrial temperature range (-40°C to +85°C).
