g) RSSI_ACQ Input signal rising edge will trigger RSSI sampling, and falling edge will trigger internal digital RSSI information written to I2C. It is recommended that host shall not trigger RSSI_ACQ input again until RSSI data is valid in I2C from previous RSSI trigger. h) RSSI DDM working range is between -8 to -30 dBm. RSSI DDM accuracy is better than +/- 3dB for input power levels between -10 to -30 dBm, the accuracy reduces to +/- 5dBm for power levels larger than -10dBm. 20550 Nordhoff St. • Chatsworth, CA 91311 • tel: 818.773.9044 • fax: 818.576.9486 9F, No 81, Shui Lee Rd. • Hsinchu, Taiwan, R.O.C. • tel: 886.3.5169222 • fax: 886.3.5169213
