Internal VCO and Clock Distribution Internal VCO and Clock Distribution When using the internal VCO and PLL, the VCO divider must be employed to ensure that the frequency presented to the channel dividers does not exceed their specified maximum frequency of 1600 MHz (see Table 3). The internal PLL uses an external loop filter to set the loop bandwidth. The external loop filter is also crucial to the loop stability. When using the internal VCO, it is necessary to calibrate the VCO (Register 0x018[0]) to ensure optimal performance. For internal VCO and clock distribution applications, use the register settings that are shown in Table 24. Table 24. Settings When Using Internal VCO Register Function 0x010[1:0] = 00b PLL normal operation (PLL on). 0x010 to 0x01D PLL settings. Select and enable a reference input; set R, N (P, A, B), PFD polarity, and ICP according to the intended loop configuration. 0x018[0] = 0b, 0x232[0] = 1b Reset VCO calibration. This is not required the first time after power-up, but it must be performed subsequently. 0x1E0[2:0] Set VCO divider to divide-by-2, divide-by-3, divide-by-4, divide-by-5, and divide-by-6. 0x1E1[0] = 0b Use the VCO divider as the source for the distribution section. 0x1E1[1] = 1b Select VCO as the source. 0x018[0] = 1b, 0x232[0] = 1b Initiate VCO calibration. |
