2.0 Programming Description (Continued)
2.2.2
MAIN_R REGISTER
If the Control Bits (CTL [1:0]) are 1 0 when LE transitions high, data is transferred from the 18-bit shift register into a latch which
sets the Main PLL 12-bit R counter divide ratio and various control functions. The divide ratio is programmed using the bits
MAIN_R_CNTR as shown in table 2.2.3. The divider ratio must be
≥ 2. The charge pump control word (CP_WORD[3:0] ) sets the
charge pump gain and the phase detector polarity as detailed in 2.4.

2.3.1
AUX_N Register
If the Control Bits ( CTL[1:0]) are 0 1 when LE transitions high, data is transferred from the 18-bit shift register into the AUX_N
register latch which sets the Aux PLL 16-bit programmable N counter value. The AUX_N counter is a 16-bit counter which is fully
programmable from 240 to 65,535 for 1.1 GHz option or from 56 to 32,767 for 500 MHz option. The AUX_N register consists of
the 4-bit swallow counter (AUX_A_CNTR), the 12-bit programmable counter (AUX_B_CNTR). Serial data format is shown below.
The divide ratio (AUX_N_CNTR [13:0]) must be
≥ 240 (1.1 GHz option) or ≥ 56 (500 MHz option) for a continuous divide range.
The Aux PLL N divide ratio is programmed using the bits AUX_A_CNTR, AUX_B_CNTR as shown in tables 2.3.2.
