Functional Description The DS92LV18 combines a serializer and deserializer onto a single chip. The serializer accepts an 18-bit LVCMOS or LVTTL data bus and transforms it into a BLVDS serial data stream with embedded clock information. The deserializer then recovers ...
Page 14
Resynchronization (Continued) The user can choose to resynchronize to the random data stream or to force fast synchronization by pulsing the Seri- alizer’s SYNC pin. Lock times depend on serial data stream characteristics. The primary constraint on the "random" lock ...

Application Information RECOVERING FROM LOCK LOSS In the case where the Serializer loses lock during data transmission cycles of data that were previously received could be invalid. This is due to a delay in the lock detection ...

Application Information PVDD = PLL SECTION POWER SUPPLY The PVDD pin supplies the PLL circuit. Note that the DS92LV18 has two separate PLL and supply pins. The PLL(s) require clean power for the minimization of Jitter. A supply noise frequency ...
