4. Closing a DIP switch on SW2, SW3, and

SW4 towards the label sets the CS61583 control

pin of the same name to logic 1.

5. When performing a manual loopback of the

recovered signal to the transmit signal at the

BNC connectors, the recovered data must be

valid on the falling edge of RCLK to properly

latch the data in the transmit direction. To

accomplish this, the SW2 switch position labeled

"CLKE" must be closed (logic 1).

6. Jumpers can be placed on headers J9 and J12

to provide a ground reference on TRING for

75Ω coax E1 applications.

7. Properly terminate TTIP/TRING when

evaluating the transmit output pulse shape. For

more information concerning pulse shape

evaluation, refer to the Crystal application note

entitled "Measurement and Evaluation of Pulse

Shapes in T1/E1 Transmission Systems."
