DS1087LU-13C/T&R is a CLK GEN/PLL/FS application field and timing chip specifically designed for high performance clock generation and distribution. It is widely used in a variety of applications, including high speed data processing, embedded system running and communications. By providing excellent performance and rugged construction, it ensures that the clock outputs stay accurate, even under tough environmental conditions.

The DS1087LU-13C/T&R contains a Phase-Locked Loop (PLL) circuit with a clock multiplier, low jitter internal oscillator, two total cycle prescalers, one divide-by-four prescaler, one reference output frequency divider, and general purpose logic functions. The PLL in this device is designed to perform self-contained oscillation, which simplifies the frequency setting process. The reference frequency is provided either through external sources – such as crystals, oscillators, and precision frequency standards – or through an internal oscillator. The PLL is also capable of supporting multiple clock frequencies for a variety of applications.

In order to generate the various clock frequencies from the PLL, the device includes the dual total cycle prescalers. This allows the user to generate multiple frequencies from a limited PLL range. It also allows for a wider range of clock frequencies to be generated from different sources. Additionally, the divide-by-four prescaler allows for more efficient operation when multiple frequencies are needed.

In addition to the clock generation and distribution functions, the DS1087LU-13C/T&R also provides a reference output frequency divider. This feature allows the user to generate a reference clock frequency from a limited PLL range. The reference output frequency divider has different power settings in order to adjust the frequency of the reference output. The reference output is also adjustable and has a range of 2 to 256 multiples of the reference input frequency.

The general purpose logic functions built into the chip make it ideal for applications such as clocking, memory and Mezzanine support, dual port RAM interfacing, CRT display interfacing, and digital source and sink drivers. The logic blocks are also compatible with most ASICs and System-On-Chip (SOC) designs, allowing for further integration.

The benefits of using the DS1087LU-13C/T&R as a clock generator include a wide range of available operating frequencies, an extended temperature range, and an easy-to-use and cost effective design. The chip is versatile enough to provide support for multiple clock frequencies, provide reliable and low-jitter operation, and help reduce system power consumption. With its high performance and durability, the DS1087LU-13C/T&R is the ideal choice for clock generation and distribution in a wide range of applications.
