3.2 Pin Configuration

Table 3-1 provides an overview of the CC1020 device pinout.

Table 3-1 Pin Attributes(1)(2)

PIN NO. PIN NAME TYPE DESCRIPTION
— AGND Ground (analog) Exposed die attached pad. Must be soldered to a solid ground plane as this is the ground connection for all analog modules. See Section 6.3 for more details.
1 PCLK Digital input Programming clock for SPI configuration interface
2 PDI Digital input Programming data input for SPI configuration interface
3 PDO Digital output Programming data output for SPI configuration interface
4 DGND Ground (digital) Ground connection (0 V) for digital modules and digital I/O
5 DVDD Power (digital) Power supply (3 V typical) for digital modules and digital I/O
6 DGND Ground (digital) Ground connection (0 V) for digital modules (substrate)
7 DCLK Digital output Clock for data in both receive and transmit mode.
Can be used as receive data output in asynchronous mode
8 DIO Digital input/output Data input in transmit mode; data output in receive mode.
Can also be used to start power-up sequencing in receive
9 LOCK Digital output PLL Lock indicator, active low. Output is asserted (low) when PLL is in lock. The pin can also be used as a general digital output, or as receive data output in synchronous NRZ/Manchester mode
10 XOSC_Q1 Analog input Crystal oscillator or external clock input
11 XOSC_Q2 Analog output Crystal oscillator
12 AVDD Power (analog) Power supply (3 V typical) for crystal oscillator
13 AVDD Power (analog) Power supply (3 V typical) for the IF VGA
14 LNA_EN Digital output General digital output. Can be used for controlling an external LNA if higher sensitivity is needed.
15 PA_EN Digital output General digital output. Can be used for controlling an external PA if higher output power is needed.
16 AVDD Power (analog) Power supply (3 V typical) for global bias generator and IF anti-alias filter
17 R_BIAS Analog output Connection for external precision bias resistor (82 kΩ, ±1%)
18 AVDD Power (analog) Power supply (3 V typical) for LNA input stage
19 RF_IN RF Input RF signal input from antenna (external AC-coupling)
20 AVDD Power (analog) Power supply (3 V typical) for LNA
21 RF_OUT RF output RF signal output to antenna
22 AVDD Power (analog) Power supply (3 V typical) for LO buffers, mixers, prescaler, and first PA stage
23 AVDD Power (analog) Power supply (3 V typical) for VCO
24 VC Analog input VCO control voltage input from external loop filter
25 AGND Ground (analog) Ground connection (0 V) for analog modules (guard)
26 AD_REF Power (analog) 3 V reference input for ADC
27 AVDD Power (analog) Power supply (3 V typical) for charge pump and phase detector
28 CHP_OUT Analog output PLL charge pump output to external loop filter
29 AVDD Power (analog) Power supply (3 V typical) for ADC
30 DGND Ground (digital) Ground connection (0 V) for digital modules (guard)
31 DVDD Power (digital) Power supply connection (3 V typical) for digital modules
32 PSEL Digital input Programming chip select, active low, for configuration interface. Internal pullup resistor.
(1) DCLK, DIO and LOCK are high-impedance (3-state) in power down (BIAS_PD = 1 in the MAIN register).
(2) The exposed die attached pad must be soldered to a solid ground plane as this is the main ground connection for the chip.
