8-Bit, 500MSPS A/D Converter

ISLA118P50

Features

• 1.15GHz Analog Input Bandwidth

• 90fs Clock Jitter

The ISLA118P50 is a low-power, high-performance,

500MSPS analog-to-digital converter designed with

Intersil’s proprietary FemtoCharge® technology on a

standard CMOS process. The ISLA118P50 is part of a

pin-compatible portfolio of 8, 10 and 12-bit A/Ds. This

device an upgrade of the KAD551XP-50 product family

and is pin similar.

• Automatic Fine Interleave Correction Calibration

• Multiple Chip Time Alignment Support via the

Synchronous Clock Divider Reset

• Programmable Gain, Offset and Skew control

• Over-Range Indicator

The device utilizes two time-interleaved 250MSPS unit

A/Ds 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 fine correction of offset, gain,

and sample time skew mismatches between the unit

A/Ds to optimize performance. No external interleaving

algorithm is required.

• Clock Phase Selection

• Nap and Sleep Modes

• Two’s Complement, Gray Code or Binary Data

Format

• DDR LVDS-Compatible or LVCMOS Outputs

• Programmable Test Patterns and Internal

Temperature Sensor

A serial peripheral interface (SPI) port allows for

extensive configurability of the A/D. The SPI also controls

the interleave correction circuitry, allowing the system to

issue continuous calibration commands as well as

configure many dynamic parameters.

Applications

• Radar and Electronic/Signal Intelligence

• Broadband Communications

• High-Performance Data Acquisition

Digital output data is presented in selectable LVDS or

CMOS formats. The ISLA118P50 is available in a

72-contact QFN package with an exposed paddle.

Performance is specified over the full industrial

temperature range (-40°C to +85°C).
