Microchip Technology, Inc. Clock Generators, PLLs, Frequency Synthesizers SY89430VZC

The SY89430VZC is a programmable frequency synthesizer designed for applications requiring precise clock generation. It operates with a power supply of either 5V or 3.3V and supports output frequencies ranging from 50MHz to 950MHz with differential PECL outputs. The device features a low output jitter of ±25ps peak-to-peak and minimal frequency overshoot, making it suitable for high-performance computing and advanced communication systems. This synthesizer utilizes a synthesized architecture with both serial and parallel interfaces, allowing for flexible integration into various designs. The internal voltage-controlled oscillator (VCO) can operate between 400MHz and 950MHz, and the output frequency can be divided by factors of 1, 2, 4, or 8. With an external 16MHz quartz crystal, the output frequency can be adjusted in 1MHz increments. The SY89430VZC is available in a 28-pin SOIC package, making it compatible with a range of circuit layouts. It is ideal for use in workstations, graphics pixel clocks, RISC CPU clocks, and other processor-based applications.
