LTC2194IUKG#PBF

LINEAR TECHNOLOGY LTC2194IUKG#PBF Analogue to Digital Converter, 16Bit, 105MSPS, Single, 1.7V, 1.9V, QFN

The is a 2-channel 16-bit low power dual Analog-to-digital Converter ADC designed for digitizing high frequency, wide dynamic range signals. It is perfect for demanding communications applications with AC performance that includes 76.8dB SNR and 90dB spurious free dynamic range SFDR. Ultralow jitter of 0.07psRMS allows under-sampling of IF frequencies with excellent noise performance. To minimize the number of data lines the digital outputs are serial LVDS. Each channel outputs two bits or four bits at a time. At lower sampling rates there is one bit per channel option. The LVDS drivers have optional internal termination and adjustable output levels to ensure clean signal integrity. The ENC+ and ENC- inputs may be driven differentially or single-ended with a sine wave, PECL, LVDS, TTL or CMOS inputs. An internal clock duty cycle stabilizer allows high performance at full speed for a wide range of clock duty cycles.
