Terminal Description
| TERMINAL NAME | TERMINAL NO. |
TERMINAL TYPE (1)
|
FUNCTION |
|---|---|---|---|
| SCLK | 1 | DO | SPI clock input. SCLK is used to clock-out/clock-in the data from/into the chip |
| CSB | 2 | DI | SPI CSB(Chip Select Bar). Multiple devices can be connected on the same SPI bus and CSB can be used to select the device to be communicated with |
| SDI | 3 | DI | SPI Slave Data In (Master Out Slave In). This should be connected to the Master Out Slave In of the master |
| VIO | 4 | P | Digital IO Supply |
| SDO | 5 | DO | SPI Slave Data Out (Master In Slave Out).It is high impedance when CSB is high |
| DGND | 6 | P | Digital ground |
| CFB | 7 | A | LDC filter capacitor |
| CFA | 8 | A | LDC filter capacitor |
| INA | 9 | A | External LC Tank. Connect to external LC tank |
| INB | 10 | A | External LC Tank. Connect to external LC tank |
| GND | 11 | P | Analog ground |
| VDD | 12 | P | Analog supply |
| CLDO | 13 | A | LDO bypass capacitor. A 56nF capacitor should be connected from this Terminal to GND |
| TBCLK | 14 | DI | External time-base clock |
| N/C | 15 | N/C | No Connection |
| INTB | 16 | DO | Configurable interrupt. This Terminal can be configured to behave in 3 different ways by programing the INT Terminal mode register. Either threshold detect, wakeup, or DRDYB |
| DAP | 17 | P | Connect to GND |
