The four paths for T4 DPLL output are as follows:
T4 selected input clock is compared with a T4 DPLL output for DPLL
• 77.76 MHz path - outputs a 77.76 MHz clock;
• 16E1/16T1 path - outputs a 16E1 or 16T1 clock, as selected by
• GSM/GPS/16E1/16T1 path - outputs an GSM, GPS, 16E1 or
• 12E1/24T1/E3/T3 path - outputs a 12E1, 24T1, E3 or T3 clock,
