Description
Digital serial RX data interface enable input or I analog output. This pin is
multiplexed between analog and digital RX interface modes. The S_MODE
bit sets the interface mode. Digital input or buffered analog output.
Receive path enable. Receive circuitry is active when a logic 1 is applied to
this pin. Digital input with weak pulldown.
Lock detect/test digital output. This pin is multiplexed between various
internal signals on the IC as defined by the TMUX and TEN bits. Digital out-
put.
Serial data interface clock input. Digital input.
Serial data interface data input. Digital input.
Serial data interface select input. The serial interface accepts clock and
data when SSB is at a logic 0 (active low). Digital input with weak
pullup.
Modulation clock input/output or TXQB transmit analog input. This pin is
multiplexed between analog and digital TX interface modes. The TXAD bit
sets the interface mode. The TXD_MODE bit determines the direction of
the pin in digital mode. Digital input, digital output, or analog input.
Modulation data input or TXQ transmit analog input. This pin is multiplexed
between analog and digital TX interface modes. The TXAD bit sets the inter-
face mode. Digital input or analog input.
Modulation sync input/output or TXIB transmit analog input. This pin is
multiplexed between analog and digital TX interface modes. The TXAD bit
sets the interface mode. Digital input/output or analog input.
TXI transmit analog input.
