Features & Applications

Semtech Corporation is a leading supplier of high-quality analog and mixed-signal semiconductor products.  The company is dedicated to providing customers with proprietary solutions and breakthrough technology in power management, protection, advanced communications, human interface, test & measurement, as well as wireless and sensing products.  The Company's integrated circuits (ICs) are employed in communications, computer and computer-peripheral, automated test equipment, industrial and other commercial applications.

SX1781 is a high-performance integer-N frequency synthesizer with built-in phase lock loop (PLL) circuits, including a voltage controlled oscillator (VCO) and loop filter. The SX1781 can generate a frequency output range of 1.2 GHz to 1.4 GHz with an ultra low phase noise characteristics and a very fast settling time. Additionally, the output power level of the device can be programmed to as high as +5dBm.

The chip contributes to environmentally friendly designs with one of the industry’s lowest power consumption levels and with an ultra low power sleep mode for low leakage. The small footprint of the SX1781 represents 36% in board real estate reduction when compared to competitive alternatives, and even more when used to replace a discrete PLL design. The part is RoHS & WEEE compliant, which contributes to hazardous waste reduction.
