ADF4169CCPZ

Analog Devices · Clock Generators / Frequency Synthesizers / PLL · LFCSP-24(4x4)

ADF4169CCPZ from Analog Devices, in a LFCSP-24(4x4). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 CPGND power_in Charge pump ground, the ground return path for the charge pump.
2 AGND power_in Analog ground; the exposed pad must be connected to AGND.
3 AGND power_in Analog ground; the exposed pad must be connected to AGND.
4 RFINB input Complementary RF prescaler input; decouple to the ground plane with a small bypass capacitor, typically 100 pF.
5 RFINA input RF prescaler input; a small-signal input normally ac-coupled from the VCO.
6 AVDD power_in Positive power supply for the RF section; decoupling capacitors should be placed as close as possible to the pin. Analog supply range is 2.7 V to 3.45 V.
7 AVDD power_in Positive power supply for the RF section; decoupling capacitors should be placed as close as possible to the pin. Analog supply range is 2.7 V to 3.45 V.
8 AVDD power_in Positive power supply for the RF section; decoupling capacitors should be placed as close as possible to the pin. Analog supply range is 2.7 V to 3.45 V.
9 REFIN input CMOS reference input with a nominal threshold of DVDD/2 and an equivalent input resistance of 100 kΩ; it can be driven from a TTL or CMOS crystal oscillator or ac-coupled.
10 DGND power_in Digital ground.
11 SDGND power_in Digital Σ-Δ modulator ground, the ground return path for the Σ-Δ modulator.
12 TXDATA input Transmit data pin that provides the transmitted data in FSK or PSK mode and also controls some ramping functionality.
13 CE input Chip enable (1.9 V logic); a logic low powers down the device and places the charge pump output into three-state mode.
14 CLK input Serial clock input used to clock serial data into the registers; data is latched into the input shift register on the CLK rising edge, and it is a high impedance CMOS input.
15 DATA input Serial data input loaded MSB first, with the three LSBs as control bits; it is a high impedance CMOS input.
16 LE input Load enable input; when LE is high, the data in the input shift register is loaded into one of the eight latches selected by the control bits, and it is a high impedance CMOS input.
17 MUXOUT output Multiplexer output that allows various internal signals to be accessed externally.
18 SDVDD power_in Power supply for the digital Σ-Δ modulator; decoupling capacitors should be placed as close as possible to the pin. Supply range is 1.8 V to 2 V.
19 DVDD power_in Positive power supply for the digital section; decoupling capacitors should be placed as close as possible to the pin. Supply range is 1.8 V to 2 V.
20 SW1 passive Fast lock switch.
21 SW2 passive Fast lock switch.
22 VP power_in Charge pump power supply; the voltage on this pin must be greater than or equal to AVDD. Supply range is 2.7 V to 3.45 V.
23 RSET passive A resistor between this pin and ground sets the maximum charge pump output current as ICP_MAX = 24.48/RSET; with RSET = 5.1 kΩ, ICP_MAX = 4.8 mA.
24 CP output Charge pump output that provides ±ICP to the external loop filter, which drives the external VCO.
25 EPAD power_in Exposed pad that must be connected to AGND.
