DD
Measured by ac coupling an external 1kHz source via suitable resistance to the TXOP pin.
The value specified is the average of values measured in the all "1"s and all "0"s states
Data pattern of "1111000011110000..."
Measured between the rising edge of the Tx DATACLK and the centre of the corresponding bit
at the output of the external RC network connected to TXOP
Measured at the output of the external RC network
For optimum performance, measured at RXIN for a "1111000011110000..." pattern
Measured between the centre of bit at RXIN and corresponding rising edge of the
Rx data clock
Levels are proportional to applied V
DD
Small signal measurement at 100Hz with no load on XTALN output
Timing for an external clock input to the XTAL/CLK pin
