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.
