Register 42h 7 6 5 4 3 2 1 0 0 0 0 0 0 NYQUIST ZONE W-0h W-0h W-0h W-0h W-0h R/W-0h LEGEND: R/W = Read/Write; W = Write only; -n = value after reset Table 38. Register 42h Field Descriptions Bit Field Type Reset Description 7-3 0 W 0h Must write 0 2-0 NYQUIST ZONE R/W 0h The Nyquist zone must be selected for proper interleaving correction. Nyquist refers to the device clock / 2. For a 1.0- GSPS device clock, the Nyquist frequency is 500 MHz. The CTRL NYQUIST register bit (register 4Eh, bit 7) must also be set. 000 = First Nyquist zone (0 MHz to 500 MHz) 001 = Second Nyquist zone (500 MHz to 1000 MHz) 010 = Third Nyquist zone (1000 MHz to 1500 MHz) All others = Not used 8.5.3.4.4 Register 43h (address = 43h), Main Digital Page (6800h) Figure 102. Register 43h 7 6 5 4 3 2 1 0 0 0 0 0 0 0 0 FORMAT SEL W-0h W-0h W-0h W-0h W-0h W-0h W-0h R/W-0h LEGEND: R/W = Read/Write; W = Write only; -n = value after reset Table 39. Register 43h Field Descriptions Bit Field Type Reset Description 7-1 0 W 0h Must write 0 0 FORMAT SEL R/W 0h This bit changes the output format. Set the FORMAT EN bit to enable control using this bit. 0 = Twos complement 1 = Offset binary 8.5.3.4.5 Register 44h (address = 44h), Main Digital Page (6800h) Figure 103. Register 44h 7 6 5 4 3 2 1 0 0 DIGITAL GAIN R/W-0h R/W-0h LEGEND: R/W = Read/Write; -n = value after reset Table 40. Register 44h Field Descriptions Bit Field Type Reset Description 7 0 R/W 0h Must write 0 6-0 DIGITAL GAIN R/W 0h These bits set the digital gain setting. The DIG GAIN EN register bit (register 52h, bit 0) must be enabled to use these bits. Gain in dB = 20log (digital gain / 32). 7Fh = 127 equals a digital gain of 9.5 dB. |
