Consuming a typical 1.4 Watts at 500 MSPS from a single 1.9 Volt supply, this device • Multiple ADC Synchronization Capability is specified to have no missing codes over the full • Specified No Missing Codes operating temperature range. The unique folding and • Serial Interface for Extended Control interpolating architecture, the fully differential comparator design, the innovative design of the • Fine Adjustment of Input Full-Scale Range and internal sample-and-hold amplifier and the self- Offset calibration scheme enable a very flat response of all • Duty Cycle Corrected Sample Clock dynamic parameters beyond Nyquist, producing a high 7.5 ENOB with a 250 MHz input signal and a APPLICATIONS 500 MHz sample rate while providing a 10-18 B.E.R. Output formatting is offset binary and the LVDS • Direct RF Down Conversion digital outputs are compatible with IEEE 1596.3-1996, • Digital Oscilloscopes with the exception of an adjustable common mode • Satellite Set-top boxes voltage between 0.8V and 1.2V. • Communications Systems Each converter has a 1:2 demultiplexer that feeds • Test Instrumentation two LVDS buses and reduces the output data rate on each bus to half the sampling rate. KEY SPECIFICATIONS The converter typically consumes less than 3.5 mW • Resolution: 8 Bits in the Power Down Mode and is available in a 128- lead, thermally enhanced exposed pad HLQFP and • Max Conversion Rate: 500 MSPS (min) operates over the Industrial (-40°C ≤ TA ≤ +85°C) • Bit Error Rate: 10-18 (typ) temperature range. • ENOB @ 250 MHz Input: 7.5 Bits (typ) • DNL: ±0.15 LSB (typ) • Power Consumption – Operating: 1.4 W (typ) – Power Down Mode: 3.5 mW (typ) 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
