ICS93777BFT

Clock/Timing - Application Specific

ICS93777BFT is a high accuracy, dual frequency clock Programmable Clock Generator (PCG) designed specifically for use in both the video display industry, and the security and automotive markets. The ICS93777BFT is designed to provide two output frequencies (up to 256MHz per output) derived from two independent clock sources. It is also capable of providing a wide range of diverse output formats such as LVDS, LVPECL and SSTL to facilitate connections to different types of processors and logic devices. This makes it well suited to a wide range of uses such as driving digital to analogue converters, generating precision timing signals for audio processing, and generating control signals for LCD display technology.

To facilitate a wide range of applications the ICS93777BFT is equipped with multiple programming modes. The user can select from various constant frequency output sources (such as 25, 27 and 33MHz), or define a user-defined frequency using the onboard PLL. In addition, the user can make use of the programmable input dependent operation (PDO) to further enhance the diversity of the output signals. This allows the user to extend the output frequency range from as low as 4KHz to as high as 200MHz. The ICS93777BFT can also be powered from a 5V input, making it suitable for use in many low power applications.

The ICS93777BFT also utilises Synchronous Clock Select (SCS) functionality to ensure that the correct output frequency is maintained even when the input frequency changes. This can be particularly beneficial in applications where two or more clocks are being driven from a single input signal, as it will maintain the correct frequency and duty cycle of the output clock signal regardless of the input signal frequency. The ICS93777BFT also has output slew rate limiting which reduces the chance of generating EMI by allowing the output signal to transition slowly from one level to another.

In addition to its flexibility, the ICS93777BFT also carries a host of additional features which improve its functionality and reliability. These include an on-chip oscillator, adjustable output skew to ensure that any output skew is compensated for, an adjustable current source for SSTL and LVDS output signals, and an internal 300mA power supply voltage regulator for improved power supply performance. The ICS93777BFT also has an integrated spread-spectrum clock generator designed to reduce EMI, and a wide temperature range of -20 to 85C.

Overall, the ICS93777BFT provides a flexible and reliable clock solution for a wide range of applications. Its ability to generate multiple output frequencies, as well as a wide range of output formats, makes it suitable for use in many different applications. Its features such as SCS, output slew rate limiting, adjustable output skew and spread-spectrum clock generator ensure reliable operation and improved performance in a wide range of environments. The ICS93777BFT is ideal for applications such as digital to analogue converters, precision timing signals for audio processing, and generating control signals for LCD display technology.
