1.7 Application Information

1.7.9 FastLock MODE 1 PROGRAMMING
The F[1]–F[7] bits will be denoted as (
*
) and are dependent on the desired modes of the applicable functions. To program the de-
vice for mode 1 FastLock, the F[8]–F[10] bits are programmed 100, while the N[19] bit is set to 1. The device will stay in the 4X
current mode until another N bit stream is sent with the N[19] bit reset to 0. This gives a bit stream as follows:
1.7.10 FastLock MODE 2 PROGRAMMING
Again, the F[1]–F[7] bits will be denoted as don’t care (
*
) but are dependent on the desired modes of the applicable functions.
To program the device for mode 2 FastLock, the F[8]–F[10] bits are programmed 101, while the N[19] bit is set to 1. The device
will stay in the 4X current mode for the programmed number of phase detector cycles. Bits F[11]–F[14] program this number of
cycles and are shown in Table 6 For our example, we will use 27 phase detector cycles, i.e. bits F[11]–F[14] will be 0110
. After
27 phase detector cycles, the N[19] bit returns to zero, bringing the device back to low current mode. The resulting bit stream is
as follows:
FastLock modes 3 and 4 are programmed in the same manner and give the added 4X gain increase as discussed in Section 1.3.4
FastLock modes.
