2.1. UWB PHY
This chip integrates the RF and baseband functions of a UWB PHY defined
by the standard. This version of PHY chip is packaged in 48-pin
QFN form
factor. The analog/RF section requires 1.8V and 3.3V to operate. The digital
core operates with 1.5V and the I/O voltage can support a range of 1.8V~3.3V.
2.2. UWB MAC
This MAC chip is also from RealTek which has a standard MPI interface to
communicate with a standard UWB PHY, as well as a high speed USB
interface to connect directly to a PC. This chip requires voltages
of 1.2V and
3.3V.
2.3. SPI Flash
This chip is a serial flash memory from Macronix with a capacity of 8Mb. It is
used by the MAC to store the initialization data and command sequence
required by the MAC and PHY on start up. This chip requires 3.3V only.
