LTC2170IUKG-12#PBF

LTC2170IUKG-12#PBF is a 4-channel, simultaneous sampling 12bit A/D converter designed for digitizing high-frequency, wide-dynamic range signals. They are perfect for demanding communications applications with AC performance that includes 71dB SNR and 90dB spurious free dynamic range (SFDR). An ultralow jitter of 0.15psRMS allows the undersampling of IF frequencies with excellent noise performance. The digital outputs are serial LVDS to minimize the number of data lines. Each channel outputs two bits at a time (2-lane mode) or one bit at a time (1-lane mode). The LVDS drivers have optional internal termination and adjustable output levels to ensure clean signal integrity. Applications include communications, cellular base stations, software-defined radios, portable medical imaging, multichannel data acquisition, and non-destructive testing.
