The SY89429AJC is a clock generator and frequency synthesizer from IDT (Integrated Device Technologies) with the ability to generate an exact cascade of frequency outputs. It is part of the Clock/Timing product family, which is categorized further into Clock Generators, Phase Lock Loops (PLLs), and Frequency Synthesizers. The SY89429AJC is a frequency synthesizer with fractional PLL & CDR designed for frequency generation within a wide voltage range (3.3V, 1.8V and 1V).

The SY89429AJC is suitable for a range of applications, such as home storage devices, cellular infrastructure equipment, industrial automation and computing. This device provides superior jitter performance, unparalleled jitter attenuation, ultra low power dissipation, and spread spectrum output to reduce EMI. The SY89429AJC also provides flexibility, allowing users to choose the output frequencies, divide ratios and output types for their specific application. With an on-chip Digital Lock Detect (DLD) and spread spectrum support, the SY89429AJC provides an all-in-one solution for precision clock generation and frequency synthesis.

The SY89429AJC contains a fractional PLL that is used for its frequency synthesis capabilities, automatically retrieving two input frequencies and synthesizing the desired output frequency. It also includes a Clock Distribution Register (CDR) that takes either of the frequencies from the PLL and “distributes” the clock output signals by applying divide by 1, 2 or 4 along its output pin. The output frequency can be adjusted through an I2C bus or an external Voltage Control Oscillator (VCO) pin. A Fractional Multiplier Configuration also allows the user to customize the available output frequency, by configuring the Frequency Multiplier between 0.25x and 16x of the input frequency.

The SY89429AJC also provides a non-return-to-zero (NRZ) spread spectrum output. This is useful for minimizing Electromagnetic Interference (EMI), while still providing the same desired frequency. Through the spread spectrum output, the device can output a signal with a lower amplitude, which in turn can reduce the spectral noise around the signal that would be typically caused by EMI radiation. This feature also allows for a tolerance depending upon the output frequency.

To further ensure the precision of its output frequency, the SY89429AJC contains a programmable Digital Lock Detect (DLD). This is used to detect whether the frequency of the PLL output is within the given range as programmed by the user or not. These precise control and monitoring methods make the SY89429AJC suitable for timing-sensitive applications where jitter needs to be minimized.

Other features of the SY89429AJC are its low operating power requirements for the device, configurable I/O slew rates and output drive strength. It can be provided with a wide operating temperature range, with industrial grade products up to +125oC available for special applications.

The SY89429AJC from IDT is a reliable, low cost and easy to use clock generator and frequency synthesizer. It is suitable for a wide range of applications in home storage devices, cellular infrastructure, industrial automation, and computing with its advanced fractional PLL & CDR, spread spectrum output, and programmable DLD. With its optimal design, the SY89429AJC is ideal for applications requiring precise clock generation and frequency synthesis.
