DESCRIPTION
13-14
S[0]..S[1]
PLL post-scaler/test mode select bits.
S[1] S[0]
DESCRIPTION
0
Post-scaler=1. F(CLK)=F(PLL). The output of the N1 divider
drives the LOAD output which, in turn, drives the N2 divider.
0
1
Post-scaler=2. F(CLK)=F(PLL)/2. The output of the N1 divider
drives the LOAD output which, in turn, drives the N2 divider.
1
0
Post-scaler=4. F(CLK)=F(PLL)/4. The output of the N1 divder
drives the LOAD output which, in turn, drives the N2 divider.
1
AUXEN CLOCK MODE. The AUXCLK bit drives the differential
outputs CLK+ and CLK- and the AUXN1 bit drives the LOAD
output which, in turn, drives the N2 divider.
15
AUX_CLK
When in the AUXEN clock mode, this bit controls the differential outputs.
16
AUX_N1
When in the AUXEN clock mode, this bit controls the N1 output (and
consequently the N2 output according to its programming). When not in
the AUXEN clock mode, this bit, if set to one, will override the N1 divider
modulus and output the VCO frequency divided by two [F(PLL)/2] at the
LOAD output.
17-24
N2[0]..N2[7]
Sets the modulus of the N2 divider. The input of the N2 divider is the
28
N2[8]
output of the N1 divider in all clock modes except AUXEN.
25-27
V[0]..V[2]
Sets the gain of VCO according to this table.
