The ICS95V857AK Clock/Timing - Application Specific device is designed specifically for certain applications. It is designed for applications such as stepper motor control, delay control, PWM waveform generation, timer cascade, clock control and video drive. It contains a number of features that make it an ideal choice for these applications.

The ICS95V857AK features an integrated system frequency controller that provides a real-time clock/timing reference signal when used with a 5 V crystal. It also has programmable delay and timeout settings with an adjustable output frequency and duty cycle. The device includes a separate asynchronous reset input, as well as a 32-bit divider that can generate up to a 4-MHz output frequency.

The ICS95V857AK also provides an analog-to-digital converter that utilizes a thermocouple, photo-diode or other analog signal to measure temperature and/or time. The ADC provides a 12 bit resolution and is designed for temperatures above 0°C. Additionally, the ICS95V857AK provides an integrated DVI transmitter that supports DVI video over a single-link DVI (up to 2.25 Gbps). The DVI transmitter also supports 3D video conferencing.

The ICS95V857AK’s working principle is best understood by examining the clock/timing application examples provided. In stepper motor applications the device utilizes an internal clock/timing controller to output a synchronized signal to the motor’s position sensing circuitry. The synchronized signal can then be used to accurately control the speed and position of the motor. In delay control applications, the device delivers a controlled delay between input and output signals. The delay is programmable and can range from microseconds, to milliseconds.

The device can also be used for pulse-width modulation (PWM) waveform generation. The ICS95V857AK is designed to produce a PWM signal at adjustable frequency and duty cycle. In timer cascade applications, the device serves as an extremely accurate master clock, while secondary clocks are configured to match the frequency of the master clock. In clock control applications, the device adjusts frequency and duty cycle of the output signal. Video drive applications utilize the integrated DVI transmitter to provide digital video data over a single-link DVI.

The ICS95V857AK is an excellent choice for many clock/timing related applications. Its integrated analog-to-digital converter, high resolution PWM signal generator, flexible delay control settings and integrated DVI transmitter make it an ideal solution for applications where reliable clock/timing control is required. The device’s real-time clock/timing reference signal also ensures accuracy and repeatability in applications where time is critical. The ICS95V857AK Clock/Timing – Application Specific device is an ideal choice for customers looking for an advanced clock/timing solution.
