Total device current can be estimated by summing the individual IDD_x and IDDO_x per pin for all blocks enabled in a given configuration.
Configuration A (All PLL blocks on except APLL2 is disabled): fREF = 25MHz, fXO = 48MHz, fVCO1 = 2.5GHz.
Configuration B (All PLL blocks on): fREF = 25MHz, fXO = 48.0048MHz, fVCO1 = 2.5GHz, fVCO2 = 5598.72GHz, PLL2_P1 = 3.
IDDO_x current for an operating output is the sum of mux, divider, and an output format.
For a differential input clock below 5MHz, TI recommends to disable the differential input amplitude monitor and enable at least one other monitor (frequency, window detectors) to validate the input clock.  Otherwise, consider using an LVCMOS clock for an input below 5MHz.
An output frequency over fOUT max spec is possible, but output swing can be less than VOD min specification.
PSNR is the single-sideband spur level (in dBc) measured when injecting sinusoidal noise with amplitude VN and frequency fN (between 100kHz and 1MHz) onto VDD and VDDO_x pins.
DJSPUR (ps pk-pk) = [2 × 10(dBc/20) / (π × fOUT) × 1E6], where dBc is the PSNR or SPUR level (in dBc) and fOUT is the output frequency (in MHz).
Actual loop bandwidth can be lower. The valid loop bandwidth range can be constrained by the DPLL TDC frequency used in a given configuration. 
Assumes VDD and VDDO_x supplies are ramped and XO input clock is stable in frequency and amplitude before the rising edge of PDN, PLLs start-up using serial calibration mode (PLL1 before PLL2), VCO wait timers set to 0.4ms, PLL wait timers set to 3ms, and outputs auto-mute during APLL lock only (DPLL auto-mute options disabled).
Parameter is specified for PLL outputs divided from either VCO domain.
DPLL closed-loop jitter peaking of 0.1dB or less is based on the DPLL bandwidth setting configured by the TICS Pro software tool.
Minimum limit applies for the minimum setting of the differential input amplitude monitor (xREF_LVL_SEL = 0).
Measured on the differential output waveform (OUTx_P - OUTx_N). Output with 2pF load.
To meet the jitter performance listed in the subsequent sections of this data sheet, the minimum recommended slew rate for all input clocks is 0.5V/ns. Phase noise performance begins to degrade as the clock input slew rate is reduced.  However, the device functions at slew rates down to the minimum listed.  When compared to single-ended clocks, differential clocks (LVDS, LVPECL) are less susceptible to degradation in phase noise performance at lower slew rates due to the common mode noise rejection. TI also recommended to use the highest possible slew rate for differential clocks to achieve optimal phase noise performance at the device outputs.
