PCM Interface Characteristics
The CM-8723BU supports a PCM digital audio interface that is used for transmitting digital audio/voice
data to/from the Audio Codes. Features are supported as below:
z Supports Master and Slave mode
z Programmable long/short Frame Sync
z Supports 8-bit A-law/ -law, and 13/16-bit linear PCM formats
z Supports sign-extension and zero-padding for 8-bit and 13-bit samples
z Supports padding of Audio Gain to 13-bit samples
z PCM Master Clock Output: 64, 128, 256, or 512kHz
z Supports SCO/ESCO link
PCM Format
FrameSync is the synchronizing function used to control the transfer of DAC_Data and ADC_Data. A Long
FrameSync indicates the start of ADC_Data at the rising edge of FrameSync, and a Short FrameSync
indicates the start of ADC_Data at the falling edge of FrameSync.

FCC Warning
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) This device m ay not c ause harmful int erference, a nd ( 2) th is device m ust acc ept any interference rec eived,
including interference that may cause undesired operation.
NOTE 1: T his eq uipment has been tested and fo und to c omply with t he limits for a Class B d igital d evice,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference in a resi dential installation. This equipment generates, uses and can radiate radio freque ncy energy
and, if not i nstalled and used i n accordance wit h t he instr uctions, may cause harmful in terference t o ra dio
communications. However, there is no guarantee that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception, which can be determined by turning
the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following
measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
-Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
-Consult the dealer or an experienced radio/TV technician for help.
NOTE 2 : Any ch anges or m odifications t o th is un it no t ex pressly ap proved by t he party resp onsible for
compliance could void the user's authority to operate the equipment.
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. End users
must follow the specific operating instructions for satisfying RF exposure compliance.
Note 1: Compliance of this device in all final host configurations is the responsibility of the Grantee.
OEM integrators are responsible to satisfy RF exposure requirements. SAR evaluation is valid for portable,
mobile and fixed applications.
The highest reported SAR value for body condition is 0.664W/kg respectively. This device was tested simulation
typical 5mm separation distance from the body.
Note 2: Any modifications made to the module will void the Grant of Certification, this module is limited to OEM
installation only and must not be sold to end-users, end-user has no manual instructions to remove or install the
device, only software or operating procedure shall be placed in the end-user operating manual of final products.
Note 3: The device must not transmit simultaneously with any other antenna or transmitter.
Note 4: To ensure compliance with all non-transmitter functions the host manufacturer is responsible for ensuring
compliance with the module(s) installed and fully operational. For example, if a host was previously authorized as
an unintentional radiator under the Declaration of Conformity procedure without a transmitter certified module
and a module is added, the host manufacturer is responsible for ensuring that the after the module is installed and
operational the host continues to be compliant with the Part 15B unintentional radiator requirements. Since this
may depend on the details of how the module is integrated with the host, LM Technologies Ltd. shall provide
guidance to the host manufacturer for compliance with the Part 15B requirements.
Note 5: FCC ID label on the final system must be labeled with “Contains FCC ID: VVX811-04XX” or “Contains
transmitter module FCC ID: VVX811-04XX”.
The transmitter module m ust b e installed an d used in strict ac cordance wit h t he manufacturer's ins tructions as
described in the user documentation that comes with the host product. LM Technologies Ltd. is responsible for the
compliance of the module in all final hosts.
