The 8N4S270FC-1088CDI is a programmable timer and oscillator device manufactured by Maxim Integrated. It is designed to replace multiple crystals and system clocks in applications such as microprocessors, digital audio, video, and network communications.

This device combines two frequency-locked loop (FLL) PLLs, a voltage-controlled oscillator (VCO), three crystal oscillators (XO), three clock dividers, several timers, and other logic for generating multiple clocks and timing intervals.

The 8N4S270FC-1088CDI is used in applications that require accurate timing. It has an excellent frequency stability, with a frequency deviation of 0.5 ppb/°C, and low jitter in the synthesized outputs. The device automatically handles changing temperature conditions, power interruptions, as well as varying reference clock sources.

The 8N4S270FC-1088CDI uses a single-chip solution to provide synchronous frequency synthesis and jitter attenuation for any system. It has three independent output clocks, each of which can be set to any frequency within the full range of the device. The onboard timers offer flexible clock sources and programmable duration.

The 8N4S270FC-1088CDI features a wide Input Mux Frequency Range (IMFR) of 10 kHz to 20 MHz, making it suitable for a variety of applications. It also features advanced jitter-attenuation techniques that blank out sources of noise, resulting in a low jitter output clock. This makes the device ideal for a wide range of micro-processing, digital audio, and video applications.

The 8N4S270FC-1088CDI output clocks are generated from a single reference clock. The device can program each of the three outputs with up to 32-bit PLL settings, allowing for a horizontal frequency resolution of 45 ppm or better. The maximum measured cycle-to-cycle jitter of the device is 2.0 ps. The 8N4S270FC-1088CDI also has an excellent phase noise performance, with a phase noise at 0.5 kHz of -174 dBc/Hz, making it ideal for high-performance applications.

The 8N4S270FC-1088CDI features a wide range of features that make it a perfect choice for applications that require high accuracy and stability. It has a programmable output frequency range of 800 kHz to 250 MHz and is available in a variety of pin configurations, enabling easy integration into any space-constrained design. The device also has a power-management feature that allows it to shut down when the device is not in use, consuming virtually no power.

The 8N4S270FC-1088CDI is an excellent choice for a wide range of applications. Its frequency stability, low jitter, wide IMFR and programmable outputs, as well as its low power consumption make it ideal for microprocessor, digital audio, video, and network communications applications.
