Functional Description
IDT82V3280
OUTn_DIVIDER[3:0]
Note:
1. 1 ≤ n ≤ 7. Each output is assigned a frequency divider.
2. In the APLL, the selected T0/T4 DPLL output may be multiplied. E1 = 2.048 MHz, T1 = 1.544 MHz, E3 = 34.368 MHz, T3 = 44.736 MHz. The blank cell means the configuration is
reserved.
3. The 622.08 MHz and 311.04 MHz differential signals are only output on OUT6 and OUT7.
4. The 61.44 MHz, 30.72 MHz, 15.36 MHz, 7.68 MHz and 3.84 MHz outputs are only derived from T0 APLL.
