LTM9008-14/ LTM9007-14/LTM9006-14 14-Bit, 65Msps/40Msps/ 25Msps Low Power Octal ADCs FEATURES DESCRIPTION n 8-Channel Simultaneous Sampling ADC The LTM 9008-14/LTM9007-14/LTM9006-14 are 8-chan- n nel, simultaneous sampling 14-bit A/D converters designed 73dB SNR n for digitizing high frequency, wide dynamic range signals. 90dB SFDR n AC performance includes 73dB SNR and 90dB spurious Low Power: 88mW/59mW/46mW per Channel n free dynamic range (SFDR). Low power consumption per Single 1.8V Supply n channel reduces heat in high channel count applications. Serial LVDS Outputs: 1 or 2 Bits per Channel n Integrated bypass capacitance and flowthrough pinout Selectable Input Ranges: 1V to 2V P-P P-P n reduces overall board space requirements. 800MHz Full Power Bandwidth S/H n Shutdown and Nap Modes DC specs include 1LSB INL (typ), 0.3LSB DNL (typ) n Serial SPI Port for Configuration and no missing codes over temperature. The transition n Internal Bypass Capacitance, No External noise is a low 1.2LSB . RMS Components The digital outputs are serial LVDS to minimize the num- n 140-Pin (11.25mm 9mm) BGA Package ber of data lines. Each channel outputs two bits at a time (2-lane mode). At lower sampling rates there is a one bit APPLICATIONS per channel option (1-lane mode). n Communications + The ENC and ENC inputs may be driven differentially n Cellular Base Stations or single-ended with a sine wave, PECL, LVDS, TTL, or n Software Defined Radios CMOS inputs.
