*CAUTION*

This product incorporates numerous static-sensitive components.

Always wear an ESD wrist strap and observe proper ESD handling

procedures when working with this device. Failure to observe this

precaution may result in module damage or failure.

NOTES:

1)

Center frequency measured while modulated with a 0-5V square wave.

2)

Into a 50-ohm load.

3)

LVLADJ open.

4)

Maximum power when LVLADJ open, minimum power when LVLADJ grounded.

5)

TXDATA pin modulated with a 0-5V square wave.

6)

7)

The audio bandwidth is wide to accommodate the needs of the data slicer. In audio applications, audio

quality may be improved by using a low pass filter rolling off at the maximum frequency of interest.

8)

These parameters are only characterized and not tested.

9)

The SC-PA is optimized for 0-5V modulation when sending digital data. 0-3V modulation is possible

but will slightly reduce system sensitivity and increase settling times.

10) Analog signals including audio should be AC-coupled. Signals in excess of 3V will cause distortion.

11) Time to transmitter or receiver readiness from the application of power to VIN or PDN going high.

12) Time from the TXEN going high and RXEN going low to the transmitter being ready to transmit data.

13) Time from the RXEN going high and TXEN going low to valid receiver data output.

14) Maximum time without a data transition.
