DESCRIPTIO U
The LTC®2230 and LTC2231 are 170Msps/135Msps, sampling 10-bit A/D converters designed for digitizing high frequency, wide dynamic range signals. The LTC2230/LTC2231 are perfect for demanding communications applications with AC performance that includes 61dB SNR and 75dB spurious free dynamic range for signals up to 200MHz. Ultralow jitter of 0.15psRMS allows undersampling of IF frequencies with excellent noise performance.
