8 / 49 page ![]() Data Sheet HMC832 PIN CONFIGURATION AND FUNCTION DESCRIPTIONS Figure 2. Pin Configuration Table 6. Pin Function Descriptions Pin No. Mnemonic Description 1 AVDD DC Power Supply for Analog Circuitry. 2, 5, 6, 8, 9, 11 to 14, 18 to 22, 24, 26, 34, 37, 38 NC No Connect. These pins are not connected internally; however, it is recommended to connect these pins to RF/dc ground externally. 3 VPPCP Power Supply for Charge Pump Analog Section. 4 CP Charge Pump Output. 7 VDDLS Power Supply for the Charge Pump Digital Section. 10 RVDD Reference Supply. 15 XREFP Reference Oscillator Input. 16 DVDD DC Power Supply for Digital (CMOS) Circuitry. 17 CEN PLL Subsystem Enable. Note that there is no effect on the VCO subsystem. Connect to logic high for normal operation. 23 VTUNE VCO Varactor. Tuning port input. 25 VCC2 VCO Analog Supply 2. 27 VCC1 VCO Analog Supply 1. 28 RF_N RF Negative Output. 29 RF_P RF Positive Output. 30 SEN PLL Serial Port Enable (CMOS) Logic Input. 31 SDI PLL Serial Port Data (CMOS) Logic Input. 32 SCK PLL Serial Port Clock (CMOS) Logic Input. 33 LD/SDO Lock Detect, or Serial Data, or General-Purpose (CMOS) Logic Output (GPO). 35 VCCHF DC Power Supply for Analog Circuitry. 36 VCCPS DC Power Supply for Analog Prescaler. 39 VCCPD DC Power Supply for Phase Detector. 40 BIAS External Bypass Decoupling for Precision Bias Circuits. Note: 1.920 V ± 20 mV reference voltage (BIAS) is generated internally and cannot drive an external load. It must be measured with a 10 GΩ meter, such as the Agilent 34410A; a normal 10 MΩ DVM reads erroneously. EP Exposed Pad. The exposed pad must be connected to RF/dc ground. NOTES 1. NC = NO CONNECT. DO NOT CONNECT TO THIS PIN. 2. THE EXPOSED GROUND PAD MUST BE CONNECTED TO RF/DC GROUND. 1 AVDD 2 NC 3 VPPCP 4 CP 5 NC 6 NC 7 VDDLS 8 NC 9 NC 10 RVDD 23 VTUNE 24 NC 25 VCC2 26 NC 27 VCC1 28 RF_N 29 RF_P 30 SEN 22 NC 21 NC HMC832 TOP VIEW (Not to Scale) Rev.
