ISLA110P50

ISLA110P50 10-Bit, 500MSPS A/D Converter 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. 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. 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. 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).
