5 / 15 page CY23FP12 Document #: 38-07246 Rev. *G Page 5 of 15 Table 2 lists independent functions that can be assigned to each of the four S1 and S2 combinations. When a particular S1 and S2 combination is selected, the device assumes the configuration (which is essentially a set of functions given in Table 2) that has been preassigned to that particular combination. Pull-down Enable Enables/Disables internal pulldowns on all outputs Enable Fbk Pull-down Enable Enables/Disables internal pulldowns on the feedback path (applicable to both internal and external feedback topologies) Enable Fbk Sel Selects between the internal and the external feedback topologies External Table 2. Programmable Functions for S1/S2 Combinations Function Description Default Output Enable CLKB[5:4] Enables/Disables CLKB[5:4] output pair See Table 4 on page 6 Output Enable CLKB[3:2] Enables/Disables CLKB[3:2] output pair See Table 4 on page 6 Output Enable CLKB[1:0] Enables/Disables CLKB[1:0] output pair See Table 4 on page 6 Output Enable CLKA[5:4] Enables/Disables CLKA[5:4] output pair See Table 4 on page 6 Output Enable CLKA[3:2] Enables/Disables CLKA[3:2] output pair See Table 4 on page 6 Output Enable CLKA[1:0] Enables/Disables CLKA[1:0] output pair See Table 4 on page 6 Auto Power-down Enable Enables/Disables the auto power down circuit, which monitors the reference clock rising edges and shuts down the device in case of a reference “failure.” This failure is triggered by a drift in reference frequency below a set limit. This auto power down circuit is disabled internally when one or more of the outputs are configured to be driven directly from the reference clock. Enable PLL Power-down Shuts down the PLL when the device is configured as a non-PLL fanout buffer. PLL Enabled M[7:0] Assigns an eight-bit value to reference divider –M. The divider can be any integer value from 1 to 256; however, the PLL input frequency cannot be lower than 10 MHz. 2 N[7:0] Assigns an eight-bit value to feedback divider –N. The divider can be any integer value from 1 to 256; however, the PLL input frequency cannot be lower than 10 MHz. 2 X[6:0] Assigns a seven-bit value to output divider –X. The divider can be any integer value from 5 to 130. Divide by 1,2,3, and 4 are preprogrammed on the device and can be activated by the appropriate output mux setting. 1 Divider Source Selects between the PLL output and the reference clock as the source clock for the output dividers. See Table 4 on page 6 CLKA54 Source Independently selects one out of the eight possible output dividers that will connect to the CLKA5 and CLKA4 pair. Please refer to Table 3 on page 6 for a list of divider values. Divide by 2 CLKA32 Source Independently selects one out of the eight possible output dividers that will connect to the CLKA3 and CLKA2 pair. Please refer to Table 3 on page 6 for a list of divider values. Divide by 2 CLKA10 Source Independently selects one out of the eight possible output dividers that will connect to the CLKA1 and CLKA0 pair. Please refer to Table 3 on page 6 for a list of divider values. Divide by 2 CLKB54 Source Independently selects one out of the eight possible output dividers that will connect to the CLKB5 and CLKB4 pair. Please refer to Table 3 on page 6 for a list of divider values. Divide by 2 CLKB32 Source Independently selects one out of the eight possible output dividers that will connect to the CLKB3 and CLKB2 pair. Please refer to Table 3 on page 6 for a list of divider values. Divide by 2 CLKB10 Source Independently selects one out of the eight possible output dividers that will connect to the CLKB1 and CLKB0 pair. Please refer to Table 3 on page 6 for a list of divider values. Divide by 2 Table 1. Programmable Functions Configuration Description Default [+] Feedback |
