型號(hào)： RFFC5071

類別： 集成電路

封裝： 每個(gè)

描述： The RFFC5071 is a re-configurable Frequency Conversion Device with integrated fractional-N phased locked loop (PLL) synthesizer, voltage controlled oscillator (VCO) and either one or two high linearity mixers. The fractional-N synthesizer takes advantage of an advanced sigma-delta modulator that delivers ultra-fine step sizes and low spurious products. The device can be configured to work as signal sources by bypassing the integrated mixers. Device programming is achieved via a simple 3-wire serial interface. In addition, a unique programming mode allows up to four devices to be controlled from a common serial bus. This eliminates the need for separate chip-select control lines between each device and the host controller. Up to six general purpose outputs are provided, which can be used to access internal signals (the LOCK signal, for example) or to control front end components. . 85 to 4200MHz LO Frequency range .
