  7. 4Revision History

3.16 Software must program the CDCE913 for 0-pf load capacitance

Software must program the CDCE913 for 0pf load capacitance to allow crystals to operate at their target frequency. Crystal load capacitors can be added to the oscillator circuit to allow the generated clock to output at the required nominal frequency so that this programming is not required. The default capacitance within the CDCE913 is 10pF so the capacitors C172, C173, C193, and C194 should be 8pF. Please refer to the CDCE(L)913: Flexible Low Power LVCMOS Clock Generator With SSC Support for EMI Reduction Data Manual (SCAS849) for more information. Also note that these clock generators are used to drive the Ethernet circuitry, so the same crystal accuracy requirement from Section 3.15 applies to these crystals as well.
