LTC2153-12 12-Bit 310Msps ADC
FeaTures DescripTion
n 67.6dBFS SNR The LTC®2153-12 is a 310Msps 12-bit A/D converter n 88dB SFDR designed for digitizing high frequency, wide dynamic n Low Power: 378mW Total range signals. It is perfect for demanding communications n Single 1.8V Supply applications with AC performance that includes 67.6dB n DDR LVDS Outputs SNR and 88dB spurious free dynamic range (SFDR). The n 1.32VP-P Input Range 1.25GHz input bandwidth allows the ADC to undersample n 1.25GHz Full Power Bandwidth S/H high frequencies with good performance. The latency is n Optional Clock Duty Cycle Stabilizer only six clock cycles. n Low Power Sleep and Nap Modes DC specs include ±0.6LSB INL (typ), ±0.1LSB DNL (typ) n Serial SPI Port for Configuration and no missing codes over temperature. The transition n Pin-Compatible 12-Bit Versions noise is 0.6LSBRMS. n 40-Lead (6mm × 6mm) QFN Package The digital outputs are double data rate (DDR) LVDS.
applicaTions
The ENC+ and ENC– inputs can be driven differentially with n Communications a sine wave, PECL, LVDS, TTL, or CMOS inputs. An optional n Cellular Basestations clock duty cycle stabilizer allows high performance at full n Software Defined Radios speed for a wide range of clock duty cycles. n Medical Imaging L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear n High Definition Video Technology Corporation.
