16-Bit, 250/200/130 MSPS JESD204B High Speed
Serial Output ADC
ISLA216S
The ISLA216S is a series of low-power, high-performance,
16-bit, analog-to-digital converters. Designed with
FemtoCharge™ technology on a standard CMOS process, the
series supports sampling rates of up to 250MSPS. The
ISLA216S is part of a pin-compatible family of 12-, 14-, and
16-bit A/Ds with maximum sample rates ranging from 130 to
500MSPS and shares the same analog core as Intersil's
proven ISLA216P series of ADCs. The family minimizes power
consumption while providing state-of-the art dynamic
performance, offering an optimal performance-vs-power
trade-off.
Differentiating the ISLA216S from the ISLA216P 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 uses two lanes to transmit the
conversion data. 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 ISLA216S 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).

NOTES:
3. θJA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See Tech
Brief TB379.
4. For θJC, the “case temp” location is the center of the exposed metal pad on the package underside.
5. For solder stencil layout and reflow guidelines, please see Tech Brief TB389.
CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product
reliability and result in failures not covered by warranty.
Electrical Specifications All specifications apply under the following conditions unless otherwise noted: AVDD = 1.8V, OVDD = 1.8V,
