Hardware Description
Clock Generator:
All the necessary clock rates such as Frame Sync, Bit Clock and the 256 KHz for the
W681xxxDK evaluation system are driven from a single 4.096 MHz crystal oscillator.
Frame Sync:
The Frame Sync is generated on the W681xxxDK evaluation board. J19 and J20 (SW5)
control the FSR (Frame Sync Receive) and FSX (Frame Sync Transmit) routing.
Enabling these jumpers also routes the signal to the 40-pin header (J11).
Setting Dip Switches:
Switch SW2 selects the width of the Frame Sync. The pulse width is set as a number of
BCLKs. The following number of BCLKs for Frame Sync can be set with SW2.
• 1-2-3-4-5-6-7-8
The Dip-Switch SW2 configurations are:
