Bit | Field | Type | Reset | Description |
---|---|---|---|---|
7 | CTRL NYQUIST | R/W | 0h | This bit
enables selecting the Nyquist zone using register 42h, bits 2-0. 0 = Selection disabled 1 = Selection enabled |
6 | 0 | W | 0h | Must write 0 |
5 | IMPROVE IL PERF | R/W | 0h | Improves
interleaving performance. Effective only for input frequencies that
are within +/- fs / 64 band centered at n * fs / 8 (n = 1, 2, 3 or
4). For example, at a 1-Gsps sampling rate, this bit may improve IL
performance when the input frequencies fall within +/- 15.625 MHz
band located at 125 MHz, 250 MHz, 375 MHz and 500 MHz. 0 = Default 1 = Improves IL performance for certain input frequenies |
6-0 | 0 | W | 0h | Must write 0 |
