General Description
The VSC6501 is a SMPTE-292M compatible Reclocker with 2 or 4 user configurablable 75 ohm Cable
Driver outputs which operate at 1.485Gb/s. HDTV serial data on the SDI/SDI inputs is recovered and retrans-
mitted on the SDO0/SDO0 and SDO1/SDO1 outputs. The CRU portion of the reclocker may be bypassed for
operation with non-HDTV data rates. The VSC6501 can be used to build routing switchers and video distribu-
tion amplifiers.
