Description Of PI49FCT3805DHE

The PI49FCT3805DHE is a 2-channel multiplexer that can switch between two different clock signals. It has two differential clock inputs, one low voltage enable input, and one differential clock output. Both differential clock inputs accept either single-ended or differential clock signals, with frequencies up to 150MHz. The PI49FCT3805DHE supports a wide range of supply voltages, ranging from a minimum of 1.2V to a maximum of 3.6V. The enable input has a wide voltage range, and can be driven with both logic and CMOS levels. An internal power-on reset (POR) circuit ensures that the device is reset properly even when the enable input is active.

Working Principle Of PI49FCT3805DHE

The PI49FCT3805DHE is a low-voltage multiplexer that allows two different clock signals to be switched between one output. The device has two differential clock inputs and one differential clock output. The inputs can accept either single-ended or differential signals, with maximum frequencies of up to 150MHz. The device is enabled by a logic-level, low-voltage enable signal. When the enable input is asserted, the device switches the signal from one clock input to the other. When the enable input is de-asserted, the signal is disabled and the output is held low.

The device is designed to switch quickly and reliably, with an enable-off time of just 5 ns and an input delay of 6 ns. The low voltage enable signal makes it ideal for applications at low to moderate supply voltages. The device includes an internal power-on reset circuit that ensures a proper reset even when the enable input is active.

The PI49FCT3805DHE is a robust, reliable device ideal for use in low voltage clock distribution applications. Its low enable-off time, wide enable voltage range, and fast switching make it ideal for processor, FPGA, and other low-power timing applications.
