Description
0x010 7
PFD polarity
Sets the PFD polarity. Negative polarity is for use (if needed) with external VCO/VCXO only.
The on-chip VCO requires positive polarity; Bit 7 = 0b.
0: positive (higher control voltage produces higher frequency) (default).
1: negative (higher control voltage produces lower frequency).
[6:4] CP current
Charge pump current (with CPRSET = 5.1 k).

0x011 [7:0] 14-bit R counter,
Bits[7:0] (LSB)
Reference divider LSBs—lower eight bits. The reference divider (also called the R divider or R counter) is 14 bits long.
The lower eight bits are in this register (default: 0x01).
0x012 [7:6] Unused
Unused.
[5:0] 14-bit R counter,
Bits[13:8] (MSB)
Reference divider MSBs—upper six bits. The reference divider (also called the R divider or R counter) is 14 bits long.
The upper six bits are in this register (default: 0x00).
0x013 [7:6] Unused
Unused.
[5:0] 6-bit A counter
A counter (part of N divider). The N divider is also called the feedback divider (default: 0x00).
0x014 [7:0] 13-bit B counter,
Bits[7:0] (LSB)
B counter (part of N divider)—lower eight bits. The N divider is also called the feedback divider (default: 0x03).
0x015 [7:5] Unused
Unused.
[4:0] 13-bit B counter,
Bits[12:8] (MSB)
B counter (part of N divider)—upper five bits. The N divider is also called the feedback divider (default: 0x00).
0x016 7
Set CP pin
to VCP/2
Sets the CP pin to one-half of the VCP supply voltage.
0: CP normal operation (default).
1: CP pin set to VCP/2.
6
Reset R counter Resets R counter (R divider).
0: normal (default).
1: holds R counter in reset.
5
Reset A and B
counters
Resets A and B counters (part of N divider).
0: normal (default).
1: holds A and B counters in reset.
4
Reset all
counters
Resets R, A, and B counters.
0: normal (default).
1: holds R, A, and B counters in reset.
3
B counter bypass B counter bypass. This is valid only when operating the prescaler in FD mode.
0: normal (default).
1: B counter is set to divide-by-1. This allows the prescaler setting to determine the divide for the N divider.
