The ICS8733BY-01LF is a high edge rate, low skew, Clock/Timing Generator, which is ideal for synchronous memory systems as well as networking and communications equipment. It is designed to provide an ultra-stable clock signal with a constant output frequency even when subjected to temperature variations and noise. The ICS8733BY-01LF can be used in a variety of clock applications, including frequency division, phase-locked loop (PLL) frequency multiplication, and digital frequency synthesis.

The ICS8733BY-01LF first starts with a stable reference frequency; standard reference frequencies can range anywhere from 8 to 50 MHz. The reference frequency is then divided down to the desired output frequency via a programmable divider. The divider is set via two parallel programmable inputs with 8-bit resolution. The divider is then enabled, allowing the device to provide a stable output frequency based on the reference frequency and division ratio.

Furthermore, the ICS8733BY-01LF features a 3-state control logic, allowing the user to control the output frequency for multiple outputs. This feature is analogous to the Phase-Locked Loop (PLL); when the logic port is applying a logic high voltage to the device, the device is locked to the reference frequency. When the logic voltage is dropped, the frequency division is prevented, and the output frequency is no longer determined by the reference frequency, allowing the user to control the output frequency.

In spite of the frequency division feature, the ICS8733BY-01LF also has the ability to perform frequency multiplication. This is achieved through the use of a voltage controlled oscillator (VCO). The VCO is fed by an input reference frequency and then multiplied to the desired output frequency. The VCO is tuned by applying a voltage to its control input, allowing the user to control the output frequency. The VCO is then coupled to a phase-detection circuit (PDC), which is set to the desired frequency either directly or via a frequency counter.

In addition to frequency division and frequency multiplication, the ICS8733BY-01LF also provides the ability to perform digital frequency synthesis. Frequency synthesis uses two different techniques: direct digital synthesis (DDS) and phase locked loop (PLL). DDS works by taking a reference clock or oscillator and using digital logic to generate a frequency that is some multiple of the reference frequency. PLL works by taking a reference clock or oscillator and using feedback circuitry to generate a frequency that is some multiple of the reference frequency.

The ICS8733BY-01LF is a versatile Clock/Timing Generator that is perfect for applications such as synchronous memory systems, networking, and communications equipment. It is capable of providing a stable output frequency based on a reference frequency, can be used in a variety of frequency division applications, and is capable of performing frequency multiplication or digital frequency synthesis. Its low skew and high edge rate make it the perfect solution for a wide range of Clock/Timing applications.
