For single-ended input this point must be decoupled to the ground plane with a ceramic bypass capacitor, typically 100 pF. 12 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 3V 13 VDDcP +5V Power Supply for charge pump digital section 14 VcccP +5V Power Supply for the charge pump analog section 15 cP charge pump output 16 VDDPFD analog Power supply for the phase frequency detector, nominally 3V 17 BiaS [1] External bypass decoupling for precision bias circuits, 1.920V ±20 mV [1] 18 aVDD analog Power supply for analog ref paths, nominally 3V 19 rEFn reference input (negative or decoupled) 20 rEFP reference input (Positive) 21 rVDD ref path supply 22 DVDDQ Digital supply for Substrate, nominally 3V 23 cE chip Enable 24 SEn Serial port latch enable input [1] notE: BiaS ref voltage cannot drive an external load. Must be measured with 10Gohm meter such as agilent 34410a, typical 10Mohm DVM will read erroneously. Pin Descriptions Information furnished by Analog Devices is believed to be accurate and reliable.
