Note 20:
Frequency accuracy is dependent on crystal oscillator chosen. The crystal must have a cumulative accuracy of < +/-20ppm to meet Bluetooth
specifications.
Note:
All RF parameters are tested prior to the antenna.
11.0 Functional Description
11.1 BASEBAND AND LINK MANAGEMENT
PROCESSORS
Baseband and Lower Link control functions are implemented
using a combination of National Semiconductor’s Com-
pactRISC 16-bit processor and the Bluetooth Lower Link
Controller. These processors operate from integrated ROM
memory and RAM and execute on-board firmware imple-
menting all Bluetooth functions.
11.1.1 Bluetooth Lower Link Controller
The integrated Bluetooth Lower Link Controller (LLC) com-
plies with the Bluetooth Specification version 2.0 and imple-
ments the following functions:
Adaptive Frequency Hopping
Interlaced Scanning
Fast Connect
Support for 1, 3, and 5 slot packet types
79 Channel hop frequency generation circuitry
Fast frequency hopping at 1600 hops per second
Power management control
Access code correlation and slot timing recovery
11.1.2 Bluetooth Upper Layer Stack
The integrated upper layer stack is prequalified and includes
the following protocol layers:
L2CAP
RFComm
SDP
11.1.3 Profile Support
The on-chip application of the LMX9838 allows full stand-
alone operation, without any Bluetooth protocol layer neces-
sary outside the module. It supports the Generic Access
Profile (GAP), the Service Discovery Application Profile
(SDAP), and the Serial Port Profile (SPP).
