TDA9917

TDA9917 8-bit, up to 250 Msample/s Analog-to-Digital Converter (ADC) Rev. 01 — 9 June 2006 Objective data sheet 1. General description The TDA9917 is a differential, high-speed, 8-bit Analog-to-Digital Converter (ADC) optimized for telecommunication transmission control systems and tape drive applications. The TDA9917 offers the selection between Low-Voltage Differential Signals (LVDS) and 1.8 V Complementary Metal Oxide Semiconductor (CMOS) levels interface for the clock. The output data interface is 1.8 V CMOS levels. It allows to sample the signal up to 250 Msample/s. All static digital inputs (CLKSEL, CCSSEL, CE_N, OTC, DEL0 and DEL1) are 1.8 V CMOS compatible. The TDA9917 offers the most possible flexible acquisition control system thanks to its programmable Complete Conversion Signal (CCS) that allows to adjust the delay of the acquisition clock and its frequency. The TDA9917 is released in HTQFP48 package. www.DataSheet4U.com 2.
