Note 6. Reference levels = 0.8V and 2.0V
Note 7. The signal CLAB can run at either 2.8MHz (1/4 system clock) or 1.4MHz (1/8 system clock)
under typical conditions. It does not have a minimum or maximum frequency, but is limited
to being 1/4 or 1/8 of the system clock frequency.
Note 8. Input setup and hold times measured with respect to clock input from A–chip (CLAB). Refer-
ence levels = 0.8V and 2.0V.
Note 9. Input setup and hold times measured with respect to subcode burst clock input from A–chip
(SCAB). Reference levels = 0.8V and 2.0V.
Note10. Output setup and hold times measured with respect to system clock output (XSYS).
Note 11. Output setup and hold times measured with respect to clock output (CLBD).
