Description
1.8V VCO supply; should be connected to VREG_OUT
Differential (with RF_N) receiver input/transmitter output
Differential (with RF_P) receiver input/transmitter output
1.8V RF supply (LNA and PA); should be connected to VREG_OUT
Differential (with RF_TX_ALT_N) transmitter output (optional)
Differential (with RF_TX_ALT_P) transmitter output (optional)
1.8V IF supply (mixers and filters); should be connected to VREG_OUT
Bias setting resistor
Analog pad supply (1.8V); should be connected to VREG_OUT
Logic-level control for external RX/TX switch
The EM260 baseband controls TX_ACTIVE and drives it high (1.8V) when in TX mode.
(Refer to Table 6 and section 4.2.2.)
Active low chip reset (internal pull-up)
Regulator output (1.8V)
Pads supply (2.1 – 3.6V)
1.8V digital core supply; should be connected to VREG_OUT
SPI Slave Select Interrupt (from Host to EM260)
When using the SPI interface, this signal must be connected to nSSEL (Pin 21)
UART Clear To Send (enables EM260 transmission)
When using the UART interface, this signal should be left unconnected if not used.
When using the SPI interface, this signal is left not connected.
UART Request To Send (enables Host transmission)
When using the UART interface, this signal should be left unconnected if not used.
SPI Data, Master Out / Slave In (from Host to EM260)
When using the UART interface, this signal is left not connected.
SPI Data, Master In / Slave Out (from EM260 to Host)
When using the UART interface, this signal is left not connected.
Pads supply (2.1 – 3.6V)
SPI Clock (from Host to EM260)
When using the UART interface, this signal is left not connected.
SPI Slave Select (from Host to EM260)
When using the UART interface, this signal is left not connected.
