OPTIONAL FUNCTION JUMPERS
The optional functions of right and left channel de-empha-
sis, the de-emphasis system clock, and right and left channel
mute are controlled by jumpers J1 through J6 as shown in

From the factory, Jumpers J1, J2, J5 and J6 are installed, as
shown below, setting the system clock at 32kHz, no de-
emphasis and no mute.

SYSTEM CLOCK OPERATION
A system clock (SYSCLK) is required for operation of the
DEM-PCM1702. If the DEM-PCM1702 is being used with
the DEM-PCM1760, the 256fs or 384fs system clock is
provided by the DEM-PCM1760 through pin 16 of the
Interface Connector, as described below. (NOTE: Care must
be taken to insure both boards are set to the same master
clock.)
If the DEM-PCM1702 is being used where it must generate
the 256fs or 384fs master clock, the appropriate crystal can
be connected to the SM5842.
COMBINATION WITH DEM-PCM1760
The DEM-PCM1702 can be directly combined with the
DEM-PCM1760 (20-bit stereo A/D conversion system).
In this case, the connector pins of the DEM-PCM1702 and
the DEM-PCM1760 are connected directly together.
The power supply for the DEM-PCM1760 is provided by
the DEM-PCM1702 and the serial digital data (within sys-
tem clock) is provided to the DEM-PCM1702 from the
DEM-PCM1760.
