Phase Lock Loop (PLL)
The MT9076 contains a PLL, which can be locked to either an input 4.096 Mhz clock or the extracted line
clock.The PLL will attenuate jitter from less than 2.5 Hz and roll-off at a rate of 20 dB/decade. Its intrinsic jitter
is less than 0.02 UI. The PLL will meet the jitter transfer characteristics as specified by AT&T document
TR 62411and the relevant recommendations as shown in Figure 12.
