14-Bit, 500/350 MSPS JESD204B High Speed Serial
Output ADC
ISLA214S50
The ISLA214S50 is a series of low-power, high-performance,
14-bit, analog-to-digital converters. Designed with
FemtoCharge technology on a standard CMOS process, the
series supports sampling rates of up to 500MSPS. The
ISLA214S50 is part of a pin-compatible family of 12-, 14-, and
16-bit A/Ds with maximum sample rates ranging from
125MSPS to 500MSPS. The family minimizes power
consumption while providing state-of-the-art dynamic
performance.
The device utilizes two time-interleaved 250MSPS unit ADCs to
achieve the ultimate sample rate of 500MSPS. A single
500MHz conversion clock is presented to the converter, and all
interleave clocking is managed internally. The proprietary
Intersil Interleave Engine (I2E) performs automatic correction
of offset, gain, and sample time mismatches between the unit
ADCs to optimize performance.
The ISLA214S50 offers a highly configurable, JESD204B-
compliant, high speed serial output link. The link offers data
rates up to 4.375 Gbps per lane and multiple packing modes.
The link can be configured to use two or three lanes to
transmit the conversion data, allowing for flexibility in the
receiver design. The JESD204 transmitter also provides
deterministic latency and multi-chip time alignment support to
satisfy complex synchronization requirements.
A serial peripheral interface (SPI) port allows for extensive
configurability of the ADC and its JESD204B transmitter
including access to its built-in link and transport-layer test
patterns as well as the programmable clock divider, enabling
2x harmonic clocking.
The ISLA214S50 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)
