Developed using an advanced 0.35µm SiGe BiCMOS process, this Integer-N synthesizer delivers outstanding integrated phase noise performance and a rapid lock time of just 150µs. It incorporates dual differential integrated VCOs with automatic center-frequency calibration. Through its direct output and programmable internal dividers (divide-by-2 and divide-by-4), the device provides comprehensive wideband coverage ranging from \u003cstrong\u003e825 MHz to 4400 MHz\u003c\/strong\u003e. Fully configurable via a dual digital bus interface (SPI and I²C), the STW81101ATR serves as a robust, low-cost monolithic alternative to discrete PLL and VCO solutions for wireless infrastructure, cellular base stations, and microwave links. The \"TR\" suffix denotes Tape and Reel packaging for automated SMT assembly.\u003c\/p\u003e\n\n\u003ch3\u003eCore Technical Specifications\u003c\/h3\u003e\n\u003ctable border=\"1\" cellpadding=\"8\" cellspacing=\"0\" style=\"width: 100%; border-collapse: collapse; text-align: left; border-color: #e0e0e0;\"\u003e\n    \u003cthead\u003e\n        \u003ctr style=\"background-color: #f8f9fa;\"\u003e\n            \u003cth style=\"width: 40%;\"\u003eParameter\u003c\/th\u003e\n            \u003cth style=\"width: 60%;\"\u003eSpecification\u003c\/th\u003e\n        \u003c\/tr\u003e\n    \u003c\/thead\u003e\n    \u003ctbody\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e\u003cstrong\u003eManufacturer\u003c\/strong\u003e\u003c\/td\u003e\n            \u003ctd\u003eSTMicroelectronics (ST)\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e\u003cstrong\u003eExact Part Number\u003c\/strong\u003e\u003c\/td\u003e\n            \u003ctd\u003eSTW81101ATR\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e\u003cstrong\u003eComponent Type\u003c\/strong\u003e\u003c\/td\u003e\n            \u003ctd\u003eInteger-N RF Frequency Synthesizer with VCOs\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e\u003cstrong\u003eFrequency Coverage\u003c\/strong\u003e\u003c\/td\u003e\n            \u003ctd\u003e825 MHz to 4.4 GHz (Multiple Sub-Bands)\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e\u003cstrong\u003eLock Time\u003c\/strong\u003e\u003c\/td\u003e\n            \u003ctd\u003e150 µs (Typical)\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e\u003cstrong\u003eControl Interface\u003c\/strong\u003e\u003c\/td\u003e\n            \u003ctd\u003eSPI and I²C Bus\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e\u003cstrong\u003eOperating Supply Voltage\u003c\/strong\u003e\u003c\/td\u003e\n            \u003ctd\u003e3.3V\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e\u003cstrong\u003ePackage \/ Case\u003c\/strong\u003e\u003c\/td\u003e\n            \u003ctd\u003e28-VFQFPN (5mm x 5mm, Exposed Pad)\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e\u003cstrong\u003ePackaging Delivery\u003c\/strong\u003e\u003c\/td\u003e\n            \u003ctd\u003eTape and Reel (TR)\u003c\/td\u003e\n        \u003c\/tr\u003e\n    \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eGlobal B2B Sourcing \u0026amp; Logistics for RF Components\u003c\/h3\u003e\n\u003cp\u003eAICCHIP specializes in the global wholesale distribution of verifiable, factory-original electronic components, including critical timing and RF ICs like the \u003cstrong\u003eSTW81101ATR\u003c\/strong\u003e.
