1. Defined for general purpose use models. For DDR/LPDDR memory applications, either dual-sample or quad-sample modes are used for read/write
separation. Quad-sample mode is used to capture rising and falling edge samples of both read and write DDR/LPDDR DQ signals for data rates up to
4 Gb/s from a single probe point. Dual-sample mode is used to capture read and write data instead of higher data rates. Using dual sample mode instead of
quad sample mode requires, double probing of DDR/LPDDR data (DQ) to capture data rates over 2.5 Gb/s.
