The IDT49FCT806APY is a high-performance Clock/Timing-Clock Buffer, Driver with an embedded differential PECL oscillator. It provides clock distribution between two logic domains that offer independent clock operations with different logic levels. In addition, it can be used to connect synchronous logic devices with different clock speeds, or to route signals from one oscillator/clock generator to several devices.

The IDT49FCT806APY consists of two identical differential PECL oscillators, with each oscillator providing differential signal outputs for feeding two identical register circuits. And each one of the register circuits outputs sequential pairs of signal pulses into the output buffer circuit, the output Buffer circuit drives buffers a differential signal that is used to feed the inputs of target devices.

In normal operation each output buffer is enabled by the external EN signal which is connected to both outputs. When the EN signal is low, the output buffer is disabled and both outputs are settled low, thus placing the target devices in sleep mode. In addition, the three-state configuration of the outputs allows the external circuitry to inhibit operation, putting the target devices in the logic low state when the EN signal is high.

The IDT49FCT806APY is used primarily in telecom and networking applications. An example could be a telecom system where one clock is used to control a data link running at 9.6 kbps in one direction, and another clock is used to control a data link running at 1.544 Mbps in the other direction. With the IDT49FCT806APY, it\'s possible to keep both data links synchronized. Since the IDT49FCT806APY can also be used to distribute the same clock to multiple devices, it can be used to provide synchronization between multiple devices, such as routers or switches, in such a network.

The clock-buffering functionality of the IDT49FCT806APY ensures that signals are quickly routed, with negligible skew and minimal ringing, between the two logic domains. This quality makes it well suited for synchronizing data links operating at different clock rates. In addition, the device can be used to perform data flow sequencing and sequencing of other timing and logic operations, such as reducing current spikes with capacitive restraints, powering up and down in circuit using enable signals, or controlling multiplexing devices for routing data to multiple destinations.

The IDT49FCT806APY’s main purpose is to control the routing, synchronization and timing of digital data signals. The device optimizes system performance and reliability by: providing a differential PECL oscillator as a clock source; buffering the signal with minimal jitter; and distributing the clock signal to multiple destinations.

In conclusion, the IDT49FCT806APY is a high-performance Clock/Timing Clock Buffer, Driver with enhanced features and the ability to provide clock distribution between two logic domains. It is primarily used in telecommunication and networking applications and is capable of buffering signals and distributing the clock signal to multiple destinations. This enables smoother system performance and synchronization among data links operating at different clock rates.
