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 1.5V and 3.3V to operate. The digital

core operates with 1.2V and the I/O voltage can support a range of 3V~3.6V.

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 2Mb. 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.
