The model 8T49N281C-998NLGI8 is designed for applications requiring flexible and cost-effective frequency synthesis.

The device is a high performance clock generator/synthesizer capable of generating any desired frequency from its reference input with a resolution of 1 Hz and accuracy of ±20ppm. The device can generate frequencies up to 2MHz with a minimum clock frequency of 2.85kHz. The 8T49N281C-998NLGI8 features a spread spectrum output; optional frequency multipliers for an extended output frequency range; a wide variety of synchronizable output frequencies; clock generation capable of handling multiple reference frequencies; a configurable crystal oscillator for frequencies up to 8MHz; a fast settling PLL for improved jitter performance; and an adjustable reference frequency.

The 8T49N281C-998NLGI8 is controlled via its serial interface. The serial interface can be used to configure the device’s output frequency, clock multiplier and output enable/disable, as well as the device’s reference frequency trim, crystal oscillator frequency and the spread spectrum enable/disable. In addition, the 8T49N281C-998NLGI8 also has a high speed, full duplex serial mode allowing for speeds up to 14.7Mbps.

The 8T49N281C-998NLGI8’s internal PLL architecture is based on a charge pump phase detector and a voltage-controlled oscillator (VCO) with an integrator. The VCO is designed to provide the required frequency resolution and sensitivity for generation of the desired output frequency with the ability to accommodate various input reference frequency sources. The device’s high-speed serial interface allows for various features to be optimized, such as clock jitter performance, initial lock-up time, and the ability to dynamically reconfigure the output frequency.

The 8T49N281C-998NLGI8 is ideal for applications that require a low cost and flexible frequency synthesis solution. It is suitable for use in a wide variety of applications, including automotive entertainment systems, communications systems, GPS systems, industrial control, and security systems. The device’s low cost makes it well suited for cost-sensitive applications, while its robust performance and wide range of features make it an ideal choice for more sophisticated applications.
