Ethernet data rates.
The integrated CRU Phase Locked Loop (PLL) recovers the high-
speed clock from the input Non-Return to Zero (NRZ) data signal.
The integrated CMU PLL multiplies a low-speed reference clock to
provide the high-speed serial line clock for internal logic and output
retiming. Both CRU and CMU can be bypassed to accommodate
rates not supported by the PLLs. The parallel interface incorporates
an on-board FIFO with auto-reset to eliminating interfacetiming
issues. The devices support serial looptiming as well as Facility,
Equipment, and Split loopback modes.
The VSC8142, VSC8145 and VSC8147 exceed the Telecordia and
ITU-T standards for jitter generation, tolerance and transfer
providing ample design margin.
dissipation, along with the thermally-enhance packages, eliminates
the need for external heatsinks and allow the devices to be used in
diverse operating environments.
