Table 9: Operating Characteristics
Operating Characteristics Notes:
1. Not including current drawn from the CMX589A pins by external circuitry. See Absolute Maximum
Ratings.
2. For VIN in the range VSS to VDD.
3. For a load of 10KΩ or greater. Tx PS input at logic ‘0’; Tx Enable = ‘1’.
4. Data pattern of 1111000011110000…
5. Measured between the rising edge of Tx Clock and the centre of the corresponding bit at Tx Out.
6. Time between the falling edge of the Tx PS and the Tx Out voltage stabilizing to normal output levels.
7. For a load of 10kΩ or greater. Rx PS input at logic ‘0’.
8. For optimum performance, Measured at the Rx Feedback pin for an 1111000011110000… pattern.
9. Measured between the center of bit at Rx Signal In and corresponding rising edge of the Rx Clock.
10. Levels are proportional to applied VDD
11. Small signal measurement at 1.0kHz with no load on Xtal output.
12. (Tx OUT enabled DC level) – (Tx Out disabled DC level) when transmitting a repeating 11110000 bit
pattern.
