Lock Detect
MUXOUT can be programmed for two types of lock detect:
digital lock detect and analog lock detect. Digital lock detect is
active high. When LDP in the R counter latch is set to
“
0,
”
digital
lock detect is set high when the phase error on three consecutive
Phase Detector cycles is less than 15 ns. With LDP set to
“
1,
”
five
consecutive cycles of less than 15 ns are required to set the lock
detect. It will stay set high until a phase error of greater than
25 ns is detected on any subsequent PD cycle. The N-channel
open-drain analog lock detect should be operated with an external
pull-up resistor of 10 k
nominal. When lock has been detected,
this output will be high with narrow low-going pulses.
INPUT SHIFT REGISTER
The ADF4001 digital section includes a 24-bit input shift regis-
ter, a 14-bit R counter, and a 13-bit N counter. Data is clocked
into the 24-bit shift register on each rising edge of CLK. The
data is clocked in MSB first. Data is transferred from the shift
register to one of four latches on the rising edge of LE. The
destination latch is determined by the state of the two control
bits (C2, C1) in the shift register. These are the two LSBs DB1,
DB0 as shown in the timing diagram of Figure 1. The truth
table for these bits is shown in Table I. Table II shows a sum-
mary of how the latches are programmed.
