	LVCMOS output, transient, 'C _L' load, 'f' MHz output frequency, 'V' output swing	1.8 + V x f _OUT x (C _L+ 12 x 10 ^-12) x 10 ³
	LVDS output, AC-coupled with 100-Ω diff load	19.7
	HCSL output, 50-Ω load to GND on each output pin	31
Output Divide Circuitry	Integer Divider Bypass (Divide = 1)	3
	Integer Divide Enabled, Divide > 1	8
	Fractional Divider Enabled	12
	additional current when PS_A differs from PS_B	15
Total Device, CDCM6208	Device Settings (V2) PRI input enabled, set to LVDS mode SEC input XTAL Input bypass off, PRI only sent to PLL Reference clock 30.72 MHz PRI input divider set to 1 Reference input divider set to 1 Charge Pump Current = 2.5 mA VCO Frequency = 3.072 GHz PS_A = PS_B divider ration = 4 Feedback divider ratio = 25 Output divider ratio = 5 Fractional divider pre-divider = 2 Fractional divider core input frequency = 384 MHz Fractional divider value = 3.84, 5.76, 3.072, 7.68 CML outputs selected for CH0-3 (153.6 MHz) LVDS outputs selected for CH4-7 (100 MHz, 66.66 MHz, 125 MHz, 50 MHz)	(excl. I _{termination_resistors}) (1.8 V: 251 mA 2.5 V: 254 mA 3.3 V: 257 mA) (incl. I _{termination_resistors}) (1.8 V: 310 mA 2.5 V: 313 mA 3.3 V: 316 mA)
Total Device, CDCM6208	Power Down (PDN = '0')	0.35

Helpful Note: The CDCM6208 User GUI does an excellent job estimating the total device current consumption based on the actual device configuration. Therefore, TI recommends using the GUI to estimate device power consumption.

The individual supply pin current consumption for Pin mode P23 was measured to come out the following:

Table 1. Individual Supplies Measured

		Y0-1	Y2-3	Y4	Y5	Y6	Y7	SEC (V_SEC = 1.8V)	SEC (V_SEC = 2.5V)	PRI	PLL1	PLL2	VCO	DVDD	Total
