... Bluetooth physical layer. The LMX5001 also offers a low power and cost competitive solution to the Bluetooth Link Controller function. The LMX5001 can be attached to a Link Management Con- troller, or Host processor performing the Link Management function to implement a complete Bluetooth interface. Bluetooth is a world-wide recognized wireless communica- tion standard, which operates in the ISM band (2 ...

... Systick generated from the internal LMX5001 Master/Slave Counter. When low holds the LMX5001 in Idle Mode. A rising edge causes a system load After a rising edge the LMX5001 will start to load control data from and store status information to the LMC via the LCI. Reset. After Reset is released the LMX5001 will be in Idle Mode, awaiting a SYSLOAD ...

... Mode. In order to guarantee this state is achieved SYSLOAD pause must be held for a minimum pe- riod of 2 µs. In Idle Mode the LMX5001 will place the LMX3162 in a low power state, and will cease processing Bluetooth Transmit and Receive data. It will remain in this state for approxi- mately 2 µ ...

This value is used by the LMX5001 to test for an acceptable level of cor- relation between the internal Bluetooth Access Code (refer- ence Bluetooth Specification) and the Access Code from the incoming packet. If the resulting maximum correlation ex- ceeds this “ ...
