XR81102-CA02TR-F is a high performance programmable Clock and Timing (C&T) device manufactured by Exar Corporation. The XR81102-CA02TR-F combines various functions such as clock generation, clock distribution, clock and timing control, jitter attenuation, and clock buffer into one integrated package which makes it highly suitable for a wide range of applications.

The XR81102-CA02TR-F application field covers multiple industries, from the telecom and datacom spaces to military and aerospace systems. It is used in a variety of applications such as digital synchronous networks (TDM/PCM and ATM), digital video broadcast (DVB-T/T2/S/S2 and ISDB-T/TB), motion control systems, processor systems, total time and time-zone clock and more. In addition, the XR81102-CA02TR-F is well suited for applications in mobile phones and tablet PCs, providing three full-function PLLs along with a 6-to-24M programmable VCXO.

Exar’s XR81102-CA02TR-F includes a variety of features to ensure accurate and reliable performance. In addition to clock generation and distribution, the device offers jitter attenuation of both reference and output signals, providing clean and low-skew clock signals for reliable and noise-free operation. It also features an integrated programmable Crystal Oscillator (XO) with a wide range of crystal accuracy options from +/-20 ppm to +/-50 ppm.

The working principle of Exar XR81102-CA02TR-F is as follows. The device is integrated with three PLLs, which are capable of generating clock frequencies ranging from 0MHz to over 6500MHz with minimal external components. All three PLLs include a wide range of programmable options such as frequency, output format, reference (crystal or external clock), and output frequency range. Furthermore, each output can be disabled and then re-enabled independently, simplifying system operation and reducing pin count.

In addition, the XR81102-CA02TR-F features an optional output frequency range extension from DC to 1 MHz, allowing clock frequencies to be output from 0 Hz up to 6.5 GHz. For jitter attenuation and jitter reduction, the device has two different Jitter Cleaners and a Multi-Delay Line. Jitter Cleaner supports a wide range of jitter frequencies and the delay line can be configured multiple times on different time domains, helping the device to achieve a wide frequency range with very low jitter.

Lastly, the device is programmable, allowing users to customize the device according to their needs. The programming can be done over I2C, SPI, and/or PMI interfaces. The device also supports an external system clock, which can be used as the reference clock for the internal PLLs.

In conclusion, Exar XR81102-CA02TR-F is an ideal solution for a variety of Clock and Timing applications. Its various features such as clock generation, distribution, jitter attenuation, and programmability make it well suited for use in the telecom, datacom, military, and aerospace industries. By using the XR81102-CA02TR-F, designers can quickly and easily generate high-performance clock and timing signals with minimal external components.
