ISLA110P50

10-Bit, 500MSPS A/D Converter

FN7606

Rev.3.0

Jul 6, 2021

The ISLA110P50 is a low-power, high-performance, 500MSPS

analog-to-digital converter designed with Renesas’ proprietary

FemtoCharge™ technology on a standard CMOS process. The

ISLA110P50 is part of a pin-compatible portfolio of 8, 10 and

12-bit A/Ds. This device is an upgrade of the KAD551XP-50

product family and is pin similar.

Features

• 1.15GHz Analog Input Bandwidth

• 90fs Clock Jitter

• Automatic Fine Interleave Correction Calibration

• Multiple Chip Time Alignment Support via the Synchronous

Clock Divider Reset

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

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.

• Programmable Gain, Offset and Skew Control

• Over-Range Indicator

• Clock Phase Selection

• Nap and Sleep Modes

• Two’s Complement, Gray Code or Binary Data Format

• DDR LVDS-Compatible or LVCMOS Outputs

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.

• Programmable Test Patterns and Internal Temperature

Sensor

Key Specifications

• SNR = 60.6dBFS for f = 190MHz (-1dBFS)

Digital output data is presented in selectable LVDS or CMOS

formats. The ISLA110P50 is available in a 72 Ld QFN package

with an exposed paddle. Performance is specified over the full

industrial temperature range (-40°C to +85°C).

• SFDR = 80dBc for f = 190MHz (-1dBFS)

• Total Power Consumption = 441mW

Applications

• Radar and Electronic/Signal Intelligence

• Broadband Communications

• High-Performance Data Acquisition
