The LTC®2158-14 is a 2-channel simultaneous sampling 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 five clock cycles.
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.
The ENC+ and ENC– inputs can be driven differentially with a sine wave, PECL, LVDS, TTL, or CMOS inputs. An optional clock duty cycle stabilizer allows high performance at full speed for a wide range of clock duty cycles.
