It is ideal for Gigabit Ethernet.
The output clock (frequency of 156.
25 or 187.
50MHz for example) is provided from two LVPECL clock output pairs.
(Specify frequency at time of order.
) The accuracy of the output frequency is assured by the internal PLL, which phase-locks the internal VCSO to the reference input frequency (25 or 30MHz for example).
The input reference can either be an external crystal, utilizing the internal crystal oscillator, or a stable external clock source such as a packaged crystal oscillator.
