Overview
Description
The ISLA214P50 is a 14-bit, 500MSPS analog-to-digital converter designed with the Renesas proprietary FemtoCharge™ technology on a standard CMOS process. The ISLA214P50 is part of a pin-compatible portfolio of 12 to 16-bit A/Ds with maximum sample rates ranging from 130MSPS to 500MSPS. 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 Interleave Engine (I2E) performs automatic correction of offset, gain, and sample time mismatches between the unit ADCs to optimize performance. 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 offline and continuous calibration commands as well as configure many dynamic parameters. Digital output data is presented in selectable LVDS or CMOS formats. The ISLA214P50 is available in a 72 Ld QFN package with an exposed paddle. Operating from a 1. 8V supply, performance is specified across the full industrial temperature range (-40°C to +85°C).
