Bit | Field | Type | Reset | Description |
---|---|---|---|---|
15:12 | OTP_ID | R/W | 0x3 | Configurable field for identifying the OTP configuration. Can be used in I2C mode as a 4-bit spare field. This field is stored in the EFUSE. |
11:9 | SSC_CONFIG_SEL | R/W | 0x0 | SSC modulation configuration. If center-spread modulation is desired, then custom SSC configuration is required. Four preconfigured down-spread modulation depths are also available. Any other modulation depths require custom SSC configuration. This field is stored in the EFUSE. The preconfigured SSC options are specifically for 100 MHz clock outputs. For other output frequencies, TI recommends creating a custom SSC configuration. 0h: Custom SSC Configuration - see Spread Spectrum Clocking for details on creating a custom configuration. 1h: –0.10% preconfigured down-spread. 2h: –0.25% preconfigured down-spread. 3h: –0.30% preconfigured down-spread. 4h: –0.50% preconfigured down-spread. All other values: Reserved |
8 | OUT_FMT_SRC_SEL | R/W | 0x0 | Forces the FMT_ADDR pin to override the output format register settings in OTP Mode. When in I2C mode, the FMT_ADDR pin is never used for this purpose. This field is stored in the EFUSE. 0h: FMT_ADDR pin is ignored in OTP mode. 1h: FMT_ADDR pin overrides the register settings. The output format is LP-HCSL, and the termination resistor values are based on the FMT_ADDR pin state on start-up. |
7:4 | OUT1_LPHSCL_AMP_SEL | R/W | 0x3 | OUT1 output swing level when using LP-HCSL output format. This field is stored in the EFUSE. 0h: 625 mV. 1h: 647 mV. 2h: 668 mV. 3h: 690 mV. 4h: 712 mV. 5h: 733 mV. 6h: 755 mV. 7h: 777 mV. 8h: 798 mV. 9h: 820 mV. Ah: 842 mV. Bh: 863 mV. Ch: 885 mV. Dh: 907 mV. Eh: 928 mV. Fh: 950 mV. |
3:0 | OUT0_LPHSCL_AMP_SEL | R/W | 0x6 | OUT0 output swing level when using LP-HCSL output format. This field is stored in the EFUSE. 0h: 625 mV. 1h: 647 mV. 2h: 668 mV. 3h: 690 mV. 4h: 712 mV. 5h: 733 mV. 6h: 755 mV. 7h: 777 mV. 8h: 798 mV. 9h: 820 mV. Ah: 842 mV. Bh: 863 mV. Ch: 885 mV. Dh: 907 mV. Eh: 928 mV. Fh: 950 mV. |
