CPC5621-EVAL-RDL/CPC5621-EVAL-CDL LITELINK™ III Evaluation Board User’s Guide 1. Introduction Thank you for using this Clare LITELINK III evaluation board. LITELINK III evaluation boards ship with CPC5621 full-wave ring detection LITELINK III parts and in one of two configurations; resistive AC termination circuit (CPC5621-EVAL-RDL) or reactive AC termination circuit (CPC5621-EVAL-CDL). NOTE: The printed-circuit board used for LITELINK III evaluation boards is a multi-purpose board. It includes many stuff options and circuits not used when manufactured as a LITELINK III evaluation board. For more information, see Stuffing Options on page 2. 1.1 Component Locations Figure 3.

Setup 3. Using the Evaluation Board This section describes setting up the LITELINK III evaluation board prior to use. Follow these guidelines for productive use of the LITELINK evaluation board: 2.1 Connection • Make all connections to the board before applying power. • LITELINK III evaluation board circuit components are sensitive to electro-static discharge (ESD). Use normal ESD precautions when working with the LITELINK III evaluation board. The LITELINK III evaluation board uses two 0.1 inch (2.54 mm) pin headers for input and output connections, J1 and J2. Clare recommends you construct header jumpers to bring the connections out to your circuit in development Table 1: Connector J1 Connections 4. Design Notes Pin Silk Screen Use 1 1 Tip. Connect to telephone network tip lead. 2 2 Ring. Connect to telephone network ring lead. 1. The default gain setting at the factory is 0 dB. 2. OH must be de-asserted (set logic high) once at power-up for 50 ms to transfer internal gain trim values within LITELINK III. This would be normal operation in many applications. Table 2: Connector J2 Connections 5. Worldwide Operation Pin Silk Screen 1 PWR IN Input power for the LITELINK III circuit. Connect to +5 or +3.3 Vdc 2 CODEC CLK TX+ input to the LITELINK III. 3 CODEC SIN TX- input to the LITELINK III. 4 CODEC SOUT RX+ output of the LITELINK III. 5 CODEC SYNC RX- output of the LITELINK III. 6 RESET Not used. 7 OH Off hook. Assert low to take the LITELINK III circuit off hook. Select and implement a stuffing option as described below: Table 3: Stuffing Options CID Caller ID. Assert low to engage the display signal routing features of LITELINK III. 8 9 2 RING Use LITELINK III evaluation board AC termination characteristics may be changed by changing stuffing options. See Stuffing Options on page 2, CPC5621-EVALCDL Schematic on page 5, and CPC5621-EVALRDL Schematic on page 6 for more information. 5.1 Stuffing Options LITELINK III Evaluation Boards can be used to evaluate LITELINK III circuits connected to several types of host equipment and several types of telephone networks. This flexibility will often require changes to the components in the circuit. Option The output of the LITELINK III ring circuit.
