Data is taken under the following conditions: 1-PLL; 27MHz Crystal, (measured at Out3).

Frequency Tolerance:

For the FD5115T and the FD5110T devices, Pletronics recommends that the tight

tolerance be required on the PLL outputs only. In this case the reference frequency

output would only achieve ±25ppm tolerance. This will reduce the cost of the device.
