Table 4E. LVPECL DC Characteristics, VCC = 3.3V±5%, VCCO_A = VCCO_B = 2.5V±5%, VEE = 0V, TA = 0°C to 70°C

NOTE 1: Outputs terminated with 50

Table 5. Input Frequency Characteristics,

VCC = 3.3V±5%, VCCO_A = VCCO_B = 3.3V±5% or 2.5V±5%, VEE = 0V, TA = 0°C to 70°C

NOTE 1: For the input crystal and CLK/, nCLK and TEST_CLK frequency range, the M value must be set for the VCO to operate within the

560MHz to 625MHz range. Using the minimum input frequency of 12MHz, valid values of M are 47

 M  52. Using the maximum input

frequency of 40MHz, valid values of M are 14

 M  15. For N = 1, M divider value must result in a VCO frequency  625MHz.
