PRODUCTION DATA
DAC12DL3200 consists of a multi-Nyquist DAC core capable of direct transmission through the third Nyquist zone. The high output frequency capabilities are enabled by specific output waveforms that alter the output waveform response. In other words, the waveforms change the frequency response of the DAC to enhance the DAC images in alternate Nyquist zones. The output waveform can be selected in the MXMODE register. A list of output modes along with their properties and uses are provided in Table 7-1 and in the following sections. Note that TS is the period of the sampling clock provided to the DACCLK input. The output waveform responses shown in this section do not consider the effect of the DAC analog bandwidth or external passive or active signal chain components.
DAC MODE | USABLE OPERATING MODES | PASSES DC | OPTIMAL NYQUIST ZONE | PEAK THEORETICAL OUTPUT POWER(1) |
---|---|---|---|---|
Non-return-to-zero (NRZ) | Single DAC, Dual DAC | Yes | 1 | 0 dBFS |
Return-to-zero (RZ) | Single DAC, Dual DAC | Yes | 1, 2 | –6 dBFS |
Radio Frequency (RF) | Single DAC, Dual DAC | No | 2 | –2.8 dBFS |
2x Radio Frequency (2xRF) | Dual DAC with 2x DACCLK | No | 3, 4, 5 | –8.8 dBFS |
