2. Chip Architecture
Internal Architecture of KL5KUSB201 is shown in figure 2. The LSI consists of 6 major
blocks as follows.
FrontEnd block
transmits and receives USB signals.
HS DLL
block
is used to re-clock High Speed signals with internal 480MHz clock.
EBUF block
is for buffering High Speed signals.
Shared Logic block
includes such function as
NRZI decode, bit un-stuffing, CRC check, serial to parallel conversion for both High
Speed and Full Speed USB signals.
SIE_IF block
interfaces with SIE bus signals. For
Full Speed operation,
DPLL block
is used to re-clock the Full Speed signals with
