CRU clock and data signals. (In this mode the VSC8117 operates just like the VSC8111 and VSC8116). The
receive section also contains a SONET/SDH frame detector circuit which is used to provide frame pluses during
the A1, A2 boundary in the serial to parallel converter. This only occurs when OOF is high. Both internal and
external LOS functions are supported. The high speed serial signals can be made PECL compatible or LVPECL
compatible by setting the proper voltage on the V
