4 / 40 page  Pin Descriptions Pin # Name Type Description 0 GND GND The DAP pad must be grounded. 1 GND GND 2 VregRFout LDO Output LDO Output for RF output buffer. 3 VccRFout Supply (LDO Input) Supply for the RF output buffer. 4 L1 NC Do not connect this pin. 5 Lmid NC Do not connect this pin. 6 L2 NC Do not connect this pin. 7 VccVCO Supply (LDO Input) Supply for the VCO. 8 VregVCO LDO Output LDO Output for RF output buffer. 9 VrefVCO LDO Bypass LDO Bypass 10 GND GND 11 CE CMOS Chip Enable. The device needs to be programmed for this pin to properly power down the device. 12 ExtVCOin RF Input Optional input for use with an external VCO. This pin should be AC coupled if used or left open if not used. 13 VccPLL1 Supply Power supply for PLL N counter. 14 VccCP1 Supply Power supply for PLL charge pump up current. 15 Vtune High-Z Input Tuning voltage input to the VCO. 16 CPout Output Charge pump output. 17 FLout Output Fastlock output. 18 VccCP2 Supply Power supply for PLL charge pump down current. 19 VccPLL2 Supply Power supply for PLL R Counter 20 Ftest/LD Output Software controllable multiplexed CMOS output. Can be used to monitor PLL lock condition. 21 OSCin High-Z Input Oscillator input signal. If not being used with an external crystal, this input should be AC coupled. 22 OSCin* High-Z Input Complementary oscillator input signal. Can also be used with an external crystal. If not being used with an external crystal, this input should be AC coupled. 23 VccOSCin Supply Supply for the OSCin buffer. 24 RFoutEN Input Software programmable output enable pin. 25 VccFRAC Supply (LDO Input) Power Supply for the fractional circuitry. 26 VregFRAC LDO Output Regulated power supply used for the fractional delta-sigma circuitry. 27 GND GND 28 VccDig Supply Supply for digital circuitry, such the MICROWIRE. 29 VccBias Supply Supply for Bias circuitry that is for the whole chip. 30 Bypass Bypass Put a cap to the VccBias pin. 31 VccDiv Supply Supply for the output divider 32 DATA High-Z Input MICROWIRE serial data input. High impedance CMOS input. This pin must not exceed 3.45 V. 33 CLK High-Z Input MICROWIRE clock input. High impedance CMOS input. This pin is used for the digital FSK modulation feature.
