Performance will not be affected. 2 - 4, 7, 37, 39 gnd [1] these pins must be connected to rF/dC ground 5 gnd these pins and package bottom must be connected to rF/dC ground 8 VCCVCO2 [2] +5V Power Supply for VCO 40 VCCVCO1 6 VtUne Control Voltage Input. Modulation port bandwidth dependent on drive source impedance. 14 aCg aC ground. this pin must be connected to an external capacitor to ground. 15 aVCC analog Power supply pin for the rF Section. a decoupling capacitor to the ground plane should be placed as close as possible to this pin. nominally 3.3V 16 VddCP +5V Power Supply for charge pump digital section 17 VCCCP +5V Power Supply for the charge pump analog section 18 CP Charge pump output 19 VddPFd analog Power supply for the phase frequency detector, nominally 3.3V 20 BIaS [3] external bypass decoupling for precision bias circuits, 1.920V ±20 mV is generated internally 21 aVdd analog Power supply for analog ref paths, nominally 3.3V 23 reFn reference input (negative or aC coupled to gnd) 24 reFP reference input (Positive) 25 rVdd ref path supply 26 dVddQ digital supply for Substrate, nominally 3.3V 27 Ce Chip enable 28 Sen Serial port latch enable input 29 SCK Serial port clock input 30 SdI Serial port data input 31 dVdd Power supply pin for internal digital circuitry. nominally 3.3V 32 VddIO Power Supply for digital I/O driver 33 Ld_SdO Lock detect, Main Serial data Output or VCO Serial Port data Out 34 VCCPS analog Power Supply for Prescaler, nominally 3.3V 35 dVddM digital Power Supply for M-Counter, nominally 3.3V 38 rFOUt rF output (aC coupled). [1] this pin is not connected internally, however, this pin must be connected to gnd to maintain product family pin for pin compatibility. [2] this pin is not connected internally, however, this pin must be connected to Vcc to maintain product family pin for pin compatibility. [3] BIaS ref voltage (pin 20) cannot drive an external load, and must be measured with a 10 gOhm meter such as agilent 34410a; a typical 10 Mohm dVM will read erroneously.
