SY89854UMI TR

The SY89854UMI TR is an ultra low jitter Any-Rate Clock and Data Multi-Output Distribution Buffer family from Texas Instruments. It is part of a wide range of TI clock solutions, specifically integrated for synchronization and multiple output distribution applications. SY89854UMI TR is and ideal product for robust and systematic clock applications as it provides ultra-low jitter/spurs over a wide input frequency range and temperature (–40°C to +105°C).

SY89854UMI TR clock buffers, drivers, receivers and transceivers are designed to deliver clock waveforms with lowest jitters across frequency, temperature and process corners. The waveforms are generated with jitter and spurs well below 1 ps RMS plus 500 femto second cycle-to-cycle in order to meet the demands of many clock based systems. SY89854UMI TR solutions employ sophisticated clock and data solutions technologies to ensure jitter performance and deliver a variety of functions for different systems.

This ultra-low jitter buffes/drivers/transceivers is used as a master clock synthesizer for distributing and synchronizing signals across the system. It supports up to 4 chip select pins for a total of 8 output banks. The chip is programmable, allowing independent control of its input frequency, data rate and output frequency. It also contains a wide range of features including programmable skew, which can be used to accurately compensate for skew errors. Additionally, the SY89854UMI TR has an adjustable output voltage with two voltage ranges.

The SY89854UMI TR Clock Buffer, Driver, Receiver and Transceiver is designed to function as an ultra-low jitter transmitter. The receiver is a low power device that operates over a wide range of frequencies, from slightly below 3.3V to 24V, with a maximum data rate of 1.25Gbps. It is also capable of passing clock signals from input to output without introducing jitter, and is suitable for applications in the digital domains such as communication, consumer electronics, computers and information processing.

At the core of this transmitter is a low-power clock synthesis unit designed to accurately generate clocks with precise jitter performance. This unit consists of a digital adjustable delay element, a voltage-controlled oscillator, an input frequency synthesizer, a frequency multiplier, and an output multiplexer. The output multiplexer allows the clock to be distributed to four different buses, each with its own output frequency. The frequency of output clock is adjustable and can be set to any frequency that is within the frequency range of the clock buffer. The Digital Adjustable Delay element is used to reduce the cycle-to-cycle jitter and spurs.

The SY89854UMI TR is also designed for future use with PLLs, DLLs and other low-power clock components. It is also suitable for use in DPRAMs, DDR/SDRAM/MRAMs, and other deterministic systems. Its low-power design helps to reduce power consumption for applications and its wide range of features makes it an ideal choice for a range of clock-related applications.

SY89854UMI TR low jitter clock and data multi-output distribution buffer family is an ideal solution for system synchronization, especially in high-speed deterministic systems such as DPRAMs, DDR/SRAMs, and MRAMs. Its ability to precisely generate clocks with ultra-low cycle-to-cycle jitter and spurs and its programmable output enables designers to achieve optimal results with ease.
