Pin Configuration
Description
CY26049-1 is a FailSafe frequency synthesizer with a
reference clock input and two 6.312-MHz outputs. The device
provides an optimum solution for applications where
continuous operation is required in the event of a primary clock
failure. The continuous, glitch-free operation is achieved by
using a DCXO, which serves as a primary clock source. The
FailSafe control circuit synchronizes the DCXO oscillator with
the reference as long as the reference is within the pull range
of the crystal.
In the event of a reference clock failure the DCXO maintains
the last frequency of the reference clock. The unique feature
of the CY26049-1 is that the DCXO is in fact the primary
clocking source. When the reference clock is restored, the
DCXO automatically resynchronizes to the reference. The
status of the reference clock input, as detected by the
CY26049-1, is reported by the SAFE pin.
