LTC4303CMS8#PBF, a voltage translator from Linear Technology, is a device that falls into the category of interface-signal buffers, repeaters, and splitters. It is suitable for applications requiring fast translation of a signal from one voltage domain to another, or for splitting a signal into multiple voltage domains for driving a bus or other device.

The LTC4303CMS8#PBF can be used to translate a single differential or single-ended signal between either a single-ended voltage domain, such as a supply voltage (VCC), or a differential voltage domain such as a differential signaling voltage of ±1.8V to ±3.3V. The device supports level shifting of both input and output signals between 1.0V and 5.5V. It also permits the same signal to be driven in two or three voltage domains simultaneously, enabling it to be used as a splitter for driving bus-oriented devices or for generating the required supply levels for ICs within multiple power domains.

In addition, the LTC4303CMS8#PBF can be used to bridge two separate power domains and send a signal from one to the other without the need for a level translator device. This eliminates the need for external level-translation components and also eliminates the associated power losses.

The LTC4303CMS8#PBF features an adjustable output slack timer (OST) that reduces crossing clock and data jitter. The timer is triggered by an input, and can be adjusted by setting the OST pin high or low. The timer adds a logical margin to the output signal, allowing it to be increased in the event of interference or adverse conditions.

One example application of the LTC4303CMS8#PBF is to connect the signals from a system’s processor core to an ASIC or FPGA. In this case, the device can be used to shift the core supply rail to a logic supply rail, such as 1.0V or 5.5V. Additionally, it can be used to generate the required supply levels for ICs within a number of power domains, thereby ensuring that all the logic levels provided by the core remain consistent.

The LTC4303CMS8#PBF offers a low cost and power efficient solution for translating a signal between multiple voltage domains. The device also supports level shifting of both inputs and outputs, as well as simultaneous driving of the same signal in multiple power domains. The adjustable output slack timer makes it suitable for applications that require a consistent and reliable signal, while its ability to bridge two power domains eliminates the need for external level-translation components.
