11 / 44 page  Revision 1.0 11 www.national.com 6.0 Electrical Specifications (Continued) 4. The f0 = -64 dBm Bluetooth modulated signal, f1 = -39 dbm sine wave, f2 = -39 dBm Bluetooth modulated signal, f0 = 2f1 - f2, and |f2 - f1| = n x 1 MHz, in which n is 3, 4, or 5. For the typical case, n = 3. Table 15.

Typical operating conditions are at VCC = 3.3V, IOVCC = 3.3V operating voltage and 25°C ambient temperature. 2. The output power is measure at the device interface. 3. ∆F2max > 115 kHz for at least 99.9% of all ∆f2max. 4. Modulation index set between 0.28 and 0.35. 5. Not tested in production. 6. Out-of-Band spurs only exist at 2nd and 3rd harmonics of the CW frequency for each channel. Table 16.
