LTC2152-14/ LTC2151-14/LTC2150-14 14-Bit 250Msps/ 210Msps/170Msps ADCs
FEATURES DESCRIPTION
n 70dB SNR The LTC®2152-14/LTC2151-14/LTC2150-14 are 250Msps/ n 90dB SFDR 210Msps/170Msps 14-bit A/D converters designed for n Low Power: 356mW/338mW/313mW Total digitizing high frequency, wide dynamic range signals. n Single 1.8V Supply They are perfect for demanding communications applica- n DDR LVDS Outputs tions with AC performance that includes 70dB SNR and n Easy-to-Drive 1.5VP-P Input Range 90dB spurious free dynamic range (SFDR). The 1.25GHz n 1.25GHz Full Power Bandwidth S/H input bandwidth allows the ADC to undersample high n Optional Clock Duty Cycle Stabilizer frequencies with good performance. The latency is only six clock cycles. n Low Power Sleep and Nap Modes n Serial SPI Port for Configuration DC specs include ±0.85LSB INL (typ), ±0.25LSB DNL (typ) n Pin Compatible 12-Bit Versions and no missing codes over temperature. The transition n 40-Pin (6mm × 6mm) QFN Package noise is 1.82LSBRMS.
APPLICATIONS
The digital outputs are double-data rate (DDR) LVDS. n Communications The ENC+ and ENC– inputs can be driven differentially with n Cellular Basestations a sine wave, PECL, LVDS, TTL, or CMOS inputs. An optional n Software Defined Radios clock duty cycle stabilizer allows high performance at full speed for a wide range of clock duty cycles. n Medical Imaging n High Definition Video L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear Technology Corporation.
