PD# De-assertion
The time from the de-assertion of PD# or until power supply ramps to get stable clocks will be less than 1.8ms. If the drive
mode control bit for PD# tristate is programmed to '1' the stopped differential pair must first be driven high to a minimum of
200mV in less than 300 s of PD# deassertion.
3V66_4/VCH Pin Functionality
The 3V66_4/VCH pin can be configured to be a 66.66MHz modulated output or a non-spread 48MHz output. The default is
3V66 clock. The switching is controlled by Byte 5 Bit 5. If it is set to '1' this pin will output the 48MHz VCH clock. The output
will go low on the falling edge of 3V66 for a minimum of 7.49ns. Then the output will transition to 48MHz on the next rising
edge of DOT_48 clock.
