Data Flow Between Framer and MPC8560
Signal Definitions
The following signals define and control the interface between the framer and MPC8560:
CLK1.544:
Clock generates 1.544 MHz output
CLK2.048:
Clock generates 2.048 MHz output
OSCI:
Oscillator Input (crystal) This is an external clock source where the frequency is defined by
CLK_SEL[2:0].
REFA:
Reference clock output A When no Loss Of Signal (LOS) is detected, this pin outputs a
recovered clock from the clock and data recovery functions block of one of the eight links.
REFB:
Reference clock output B When no LOS is detected, this pin outputs a recovered clock
from the clock and data recovery functions block of one of the eight links.
RSCK:
Receive Side System Clock (links 1-8) In receive clock master mode, the RSCKn pins out-
put a 1.544 MHz (T1/J1)/2.048 MHz (E1) clock. In receive clock slave mode, the RSCKn pins
input a 1.544 MHz (T1/J1 only), 2.048 or 4.096 MHz clock.
