CONFIGURATION 6
SNLS143D – FEBRUARY 2003 – REVISED MARCH 2013
DS90CR485 and DS90CR486 with DC Balance OFF (DS90CR486’s BAL=Low, CON1=High, 66MHz to 133MHz)
−The input to the DS_OPT pin of the transmitter DS90CR485 in this configuration is completely ignored. In order
to initialize the deskew operation on the receiver DS90CR486, data and clcok must be applied to the transmitter
when power up. The "DESKEW" and CON1 pins on the receiver DS90CR486 must set High.
DESKEW NOT SUPPORTED
Deskew function is NOT supported in these configuration setups. The deskew feature is only supported with DC
Balance ON (BAL=High) for DS90CR484. Note that the deskew function in the DS90CR486 works in both DC
Balance and NON-DC Balance modes.
