5 / 12 page DS261DB2 55 CDB61584A Dual Line Interface Unit EVALUATION HINTS 1) The orientation of pin 1 for the CS61584A is la- beled "1" on the left side of the socket U7. 2) A jumper must not be placed on header J10 when using the CDB61584A. 3) Component locations R3-R4, R14-R15, C1, and C12 must have the correct values installed according to the application. All the necessary components are included with the evaluation board. 4) Closing a DIP switch on SW2, SW3, and SW4 towards the label sets the CS61584A control pin of the same name to logic 1. 5) When performing a manual loopback of the re- covered 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) during Hardware mode operation or the CLKE bit in the Control A reg- ister must be set to a 1 during Host mode oper- ation. 6) Jumpers can be placed on headers J9 and J12 to provide a ground reference on TRING for 75 Ω coax E1 applications. 7) Properly terminate TTIP/TRING when evalu- ating 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." |
