Data Sheet
Receive
data rates
(1) Whichever supplies the receive clock depending on the selected clock mode:
(2) NRZ, NRZI and Manchester data encoding
(3) FM0 and FM1 data encoding
(4) If Carrier Detect auto start feature enabled (not for clock modes 1, 4 and 5)
Receive Clock
externally clocked via RxCLK or XTAL1 or
internally clocked via DPLL or BRG.
(No edge relation can be measured if the internal receive clock is derived from the external clock
source by division stages (BRG) or DPLL)
