1 / 29 page ADC12C170 www.ti.com SNAS374D – DECEMBER 2006 – REVISED APRIL 2009 ADC12C170 12-Bit, 170 MSPS, 1.1 GHz Bandwidth A/D Converter with CMOS Outputs Check for Samples: ADC12C170 1 FEATURES DESCRIPTION The ADC12C170 is a high-performance CMOS 2 • 1.1 GHz Full Power Bandwidth analog-to-digital converter capable of converting • Internal Sample-and-Hold Circuit analog input signals into 12-Bit digital words at rates • Low Power Consumption up to 170 Mega Samples Per Second (MSPS). This converter uses a differential, pipelined architecture • Internal Precision 1.0V Reference with digital error correction and an on-chip sample- • Single-Ended or Differential Clock Modes and-hold circuit to minimize power consumption and • Clock Duty Cycle Stabilizer the external component count, while providing excellent dynamic performance. A unique sample- • Dual +3.3V and +1.8V Supply Operation and-hold stage yields a full-power bandwidth of 1.1 • Power-Down and Sleep Modes GHz. The ADC12C170 operates from dual +3.3V and • Offset Binary or 2's Complement Output Data +1.8V power supplies and consumes 715 mW of Format power at 170 MSPS. • Pin-Compatible: ADC14155, ADC11C125, The separate +1.8V supply for the digital output ADC11C170 interface allows lower power operation with reduced • 48-Pin WQFN Package, (7x7x0.8mm, 0.5mm noise. A power-down feature reduces the power consumption to 5 mW while still allowing fast wake-up Pin-Pitch) time to full operation. In addition there is a sleep feature which consumes 50 mW of power and has a APPLICATIONS faster wake-up time. • High IF Sampling Receivers The differential inputs provide a full scale differential • Wireless Base Station Receivers input swing equal to 2 times the reference voltage. A • Power Amplifier Linearization stable 1.0V internal voltage reference is provided, or the ADC12C170 can be operated with an external • Multi-Carrier, Multi-Mode Receivers reference. • Test and Measurement Equipment Clock mode (differential versus single-ended) and • Communications Instrumentation output data format (offset binary versus 2's • Radar Systems complement) are pin-selectable. A duty cycle stabilizer maintains performance over a wide range of KEY SPECIFICATIONS input clock duty cycles. • Resolution 12 Bits The ADC12C170 is pin compatible with the • Conversion Rate 170 MSPS ADC14155, ADC11C125 and ADC11C170. • SNR (fIN = 70 MHz) 67.2 dBFS (typ) It is available in a 48-lead WQFN package and • SFDR (fIN = 70 MHz) 85.4 dBFS (typ) operates over the industrial temperature range of −40°C to +85°C. • ENOB (fIN = 70 MHz) 10.8 bits (typ) • Full Power Bandwidth 1.1 GHz (typ) • Power Consumption 715 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.
