The ADC and the DAC of the CODEC each contain two independent
channels. Any ADC or DAC channel can be run at its own independent
sample rate.

programmed for line input.
The audio output circuitry consists of a dual differential class A-B
output st age.
Clock Input and Generation
The reference clock for the system is generated from a TCXO or
crystal input 26MHz. All internal reference clocks are generated using
a phase locked loop, which is locked to the external reference
frequency.

Federal Communication Commission Interference Statement
This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio 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 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.
FCC Caution: Any changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to operate this
equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions:
(1) This device may not cause harmful interference, and
(2) This device must accept any interference received, including interference that
may cause undesired operation.

FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with
minimum distance 20cm between the radiator & your body. This transmitter must
not be co-located or operating in conjunction with any other antenna or
transmitter.
This device is intended only for OEM integrators under the following conditions:
1. The antenna must be installed such that 20 cm is maintained between the
antenna and users, and
2. The transmitter module may not be co-located with any other transmitter or
antenna,
IMPORTANT NOTE:
In the event that these conditions can not be met (for example certain laptop
configurations or co-location with another transmitter), then the FCC authorization
is no longer considered valid and the FCC ID can not be used on the final product.
In these circumstances, the OEM integrator will be responsible for re-evaluating
the end product (including the transmitter) and obtaining a separate FCC
authorization.
End Product Labelling
This transmitter module is authorized only for use in device where the antenna
may be installed such that 20 cm may be maintained between the antenna and
users.
The final end product must be labelled in a visible area with the following:
“Contains FCC ID: ZVA04”.
Manual Information to the End User
The OEM integrator has to be aware not to provide information to the end user
regarding how to install or remove this RF module in the user’s manual of the end
product which integrates this module.
The Module must be installed in BLU-RAY DISC HOME THEATER SOUND
SYSTEM.
