SEL[2:0] Function
The IDT5V49EE703 can support up to six unique
configurations. Users may pre-programmed all these
configurations, and select the configurations using SEL[2:0]
SD/OE Pin Function
The polarity of the SD/OE signal pin can be programmed to
be either active HIGH or LOW with the SP bit (0x02). When
SP is “0” (default), the pin becomes active HIGH and when
SP is “1”, the pin becomes active LOW. The SD/OE pin can
be configured as either to shutdown the PLLs or to
enable/disable the outputs.
1 Assert to disable the outputs whose OE bits are set
2 Assert to shut down power, on the outputs and 3-level pins
