0x8A—0x8F
The bits in registers 0x8A—0x8F are used to control vari-
ous aspects of the digital jitter attenuator. Two programma-
ble terms are used to set the 2nd order loop damping factor
and natural frequency of the PLL. These terms are the gain
threshold, set by DJAGTHR-[23:0] in registers
0x8D—0x8F, and scale value, set by DJASCALE-[15:0] in
registers 0x8B—0x8C. The PLL bandwidth can be set,
using the above registers, to accommodate various system
constraints.
