83940DY-01LF is an advanced clock buffer developed by Integrated Device Technology (IDT) to support high-speed clock rates of up to 60MHz. It is an integrated, low-power chip that provides an economical solution when dealing with clock skew, power supply noise, sequence related concerns, and timing accuracy issues in high-speed applications.

This clock buffer makes clock signal buffering easier by eliminating the need for additional external buffers for high-performance FPGA and ASIC designs. It has also been successfully used in communications equipment and systems, as well as in high-speed clock distribution networks.

The 83940DY-01LF features two SMA outputs, and two selectable output delay controls that can be used to increase or decrease the output clock phase. The CMOS-compatible outputs are ac coupled, allowing for a wide range of frequencies to be used. It also has a selectable spread spectrum frequency modulation setting that allows the clock frequency to be modulated over a wide range.

The 83940DY-01LF clock buffer is ideal for applications that require stable clock signals with high accuracy, such as Ethernet switches, low-speed DDR2/3/4 memory applications, industrial control systems, and PCI Express systems. It can also be used in high-speed requirements, such as embedded memory applications, high-speed digital circuit design, and analog-to-digital converters.

The primary application field of 83940DY-01LF clock buffer is in modern high-speed communication and embedded applications, requiring clock signals to be buffered with accuracy and dependability. Its working principle is simple yet effective; it takes the input clock signal and buffers this signal up to two outputs with the enable pin, controlling the buffer enable status with a logic high input. This output signal is processed further by a pair of selectable output delay controls, before being delivered to two SMA outputs.

The output delay control pins allow for the adjustment of the output clock phase relative to the input clock. The unique spread spectrum modulation can modulate the clock frequency over a wide range, thus reducing electromagnetic interference. The output clock also includes a skew control oscillator to reduce the frequency difference between clock outputs.

The 83940DY-01LF offers an efficient, low-power solution for clock buffering due to its high-performance, and wide output clock frequency of up to 60MHz. It is able to reliably generate clock signals with low-power, and low time-to-time jitter. The spread spectrum frequency modulation control is also a useful feature, allowing for the reduction of EMI.

The 83940DY-01LF is a highly-compact, low-power clock buffer designed to be used in high-performance, high-speed applications. Its main application field lies in modern communication and embedded systems, with high clock-rates of up to 60MHz and adjustable output clock phase, due to its integrated output delay control. It is also able to reduce EMI using a spread spectrum frequency modulation feature, thus allowing for greater compatibility with other components in the system. This makes the 83940DY-01LF a reliable, dependable clock buffer for many high-speed clock applications.
