6 / 19 page FD7T Series Multi-Output CMOS Clock Oscillator May 2008 www.pletronics.com 425-776-1880 6 Output Buffers Each output buffer can have 3 modes of operation: 1) Tri State 2) Active Low 3) The signal output of the Multiplexer The output buffers for Out2 and Out3 and the output buffers Out6 and Out7 function as pairs. When selecting on the function both outputs in the pair function the same. There can be two options stored for the Output Buffers, State 0 and State 1. The eight Sx input settings can have assigned one of the two Output Buffer states for each of Output Buffer sets. This permits wired ‘OR’ of tri-state outputs, this permits setting total enable and disable functions of all outputs. Control Inputs The three inputs, S0, S1/SDA and S2/SCL can be configured in two ways. 1) Used as 3 user inputs to permit up to 8 states, Sx input setting. 2) S0 used as an input to permit up to 2 states, S0 input setting. The SDA and SCL become clock and data inputs to write to the FD7T internal setting memory. The interface follows the I 2C protocol. If the SDA and SCL are not set then the internal eePROM sets the operation. The S0, S1 and S2 input signals control and variations states allowed: Inputs PLL #1 PLL #2 PLL #3 PLL #4 Output S2 S1 S0 SS PLL SS PLL SS PLL SS PLL 123456 7 0 0 0 0/7 0/1 0/7 0/1 0/7 0/1 0/7 0/1 0/1 0/1 0/1 0/1 0/1 0/1 0/1 0 0 1 0/7 0/1 0/7 0/1 0/7 0/1 0/7 0/1 0/1 0/1 0/1 0/1 0/1 0/1 0/1 0 1 0 0/7 0/1 0/7 0/1 0/7 0/1 0/7 0/1 0/1 0/1 0/1 0/1 0/1 0/1 0/1 0 1 1 0/7 0/1 0/7 0/1 0/7 0/1 0/7 0/1 0/1 0/1 0/1 0/1 0/1 0/1 0/1 1 0 0 0/7 0/1 0/7 0/1 0/7 0/1 0/7 0/1 0/1 0/1 0/1 0/1 0/1 0/1 0/1 1 0 1 0/7 0/1 0/7 0/1 0/7 0/1 0/7 0/1 0/1 0/1 0/1 0/1 0/1 0/1 0/1 1 1 0 0/7 0/1 0/7 0/1 0/7 0/1 0/7 0/1 0/1 0/1 0/1 0/1 0/1 0/1 0/1 1 1 1 0/7 0/1 0/7 0/1 0/7 0/1 0/7 0/1 0/1 0/1 0/1 0/1 0/1 0/1 0/1 The MUX inputs are fixed independent of the Sx setting. The Divider Values are fixed independent of the Sx setting Specifying The FD7T Device For A Specific Application Pletronics provides an EXCEL spreadsheet based program that assists in defining the FD77T functions. The program only permits setting of parameters that will properly function. After defining the desired functions, this spreadsheet is sent to Pletronics and the Configuration Part Number will then be assigned. Pletronics uses the values in the spreadsheet to program the devices for shipment. |
