Notes:

1. All DC voltages are referenced to V

2. Vrms per tone, 540W load.

3. Any one frequency relative to the lowest level output tone (f<4000 Hz).

4. 0 dBm = 0.775 Vrms.

5. To 90% maximum amplitude.

Note:

1. Exceeding these ratings may permanently damage the M-993.

Absolute Maximum Ratings are stress ratings. Stresses in

excess of these ratings can cause permanent damage to

the device. Functional operation of the device at these or

any other conditions beyond those indicated in the opera-

tional sections of this data sheet is not implied. Exposure of

the device to the absolute maximum ratings for an extend-

ed period may degrade the device and effect its reliability.

6. For all supply voltages in the operating range.

7. At XOUT pin as compared to 3.579545 MHz.

8. OUTDRIVE with load >5 KW/OUTDRIVE with 540W load.

9. Crystal oscillator active.

10. Measured 90% to 10%.
