Electrical Characteristics
4.3 Transmit Path Description
For the transmit path, the TX data that was previously stored in RAM is retrieved (packet mode) or the TX
data is clocked in via the SPI (stream mode), formed into packets per the 802.15.4 PHY, spread, and then
up-converted to the transmit frequency.
If the MC13192 is in packet mode, data is processed as an entire packet. The data is first loaded into the
TX buffer. The MCU then requests that the MC13192 transmit the data. The MCU is notified via an
interrupt when the whole packet has successfully been transmitted.
In streaming mode, the data is fed to the MC13192 on a word-by-word basis with an interrupt serving as
a notification that the MC13192 is ready for more data. This continues until the whole packet is
transmitted.

Note: Maximum Ratings are those values beyond which damage to the device may occur.
Functional operation should be restricted to the limits in the Electrical Characteristics
or Recommended Operating Conditions tables.
Note: ESD protection meets Human Body Model (HBM) = 2 kV. RF input/output pins have no ESD protection.
