Functional Description RPE MUX and Fail-Safe Input The SY89465U is optimized for clock switchover applications where switching from one clock to another clock without runt pulses (short cycles) is required. It features two unique circuits: Runt-Pulse Eliminator (RPE) Circuit The ...

Case #2: Input Clock Failure: Switching from a selected clock stuck HIGH to a valid clock (RPE enabled). If CLK1 fails HIGH before the RPE MUX selects CLK2 (using the SEL pin), the switchover will occur in three stages. Note: ...

Case #3: Input Clock Failure: Switching from a selected clock stuck Low to a valid clock (RPE- enabled). If CLK1 fails LOW before the RPE MUX selects CLK2 (using the SEL pin), the switchover will occur in two stages. December ...

Case #4: Input Clock Failure: Switching from the selected clock input stuck in an undetermined state to a valid clock input (RPE-enabled). If CLK1 fails to an undetermined state (e.g., amplitude falls below the 100mV (V single-ended input limit, or ...

Enable Output (EN) Description The enable function is synchronous so that the outputs will be enabled/disabled when they are already in the LOW state. This avoids any chance of generating a runt pulse when the device is enabled/disabled as can ...

Power-On Reset (POR) Description The SY89465U includes an internal power-on reset (POR) function to ensure that the RPE logic starts known logic state once the power-supply voltage is stable. An external capacitor connected between V and the ...
