Clock generation
All system clocks are generated using the clock generator block. This contains two
high-frequency PLLs (532 MHz/400 MHz) that are divided down to produce a series of
phase-related programmable clock channels.
The STi5107 has a clock master. The Flash clock output may be phase aligned to optimize
the external bus performance of the FMI.
VCXO functionality has been integrated using a special purpose frequency synthesizer, thus
removing the need for an external varactor diode or VCXO module.
one smartcard controller,
two ASCs (UARTs) which are generally used by the smartcard controllers or for modem
application,
