n 1.25GHz Full Power Bandwidth S/H
n Optional Clock Duty Cycle Stabilizer
n Low Power Sleep and Nap Modes
n Serial SPI Port for Configuratio Pin-Compatible 12-Bit Versio 40-Lead (6mm × 6mm) QFN Package The LTC®2153-14 is a 310Msps 14-bit A/D converter
designed for digitizing high frequency, wide dynamic
range signals. It is perfect for demanding communications
applications with AC performance that includes 68.8dB
SNR and 88dB spurious free dynamic range (SFDR). The
1.25GHz input bandwidth allows the ADC to undersample
high frequencies with good performance. The latency is
only six clock cycles. n DC specs include ±1.2LSB INL (typ), ±0.35LSB DNL (typ)
and no missing codes over temperature. The transition
noise is 2.11LSBRMS.
The digital outputs are double data rate (DDR) LVDS. Applications n n n n The ENC+ and ENC– inputs can be driven differentially with …
