Theory of Operation/Technical Description – FCC ID: A8TBM77SPPSYC2A - RF circuit function: BM77SPPS05, BM77SPPS03 are based on the IS1677NM, SOC IC. The major area of the IC chip contains the 2.4GHz, Bluetooth compliant transceiver. Additionally, there is a small area on the SOC,chip dedicated to the implementation of the Bluetooth stack and the Apple MFi protocol. The two Chip Model Nos. reflect these differences in the activated digital device portions of the SOC, by disabling MFi function in Module BM77SPPS03. Both Chips have the same pin layout. The difference between the modules is as follows: Module Features Module BM77SPPS05 BM77SPPS03 model No. Feature MFi+SPP+ BT-LE SPP+BT-LE function Chip Model IS1677NM IS1677NM Note: Provides all feature MFI disabled function MFi: “Made for iPod” SPP: Bluetooth Serial Port Profile BT Audio: Bluetooth Audio Profiles BT-LE: Bluetooth 4.0 Low Energy - RF signal flow: The Data or Audio signal is encoded into a Data Stream to be the modulation input for the a 2.4GHz, Bluetooth compliant transceiver. - Description of Antenna system (Baluns, Multiplexers) The asymmetric RF output of the SoC is connected to the antenna through a filter network - Show compliance with 15.203 antenna requirements: PCB chip antenna not changeable by end user. - Description of all modulation schemes used in the product: BT-LE: GFSK BT BDR and EDR: GFSK, π /4 PSK, 8DPSK
