Single-chip design forms complete PLL synthesizer
Article Abstract:
Silicon Laboratories Inc of Austin, TX, has introduced a new product that simplifies and meets the wireless industry's demand for compact and low current consumption systems. Called the Si4132 dual-band frequency synthesizer integrated circuit (IC), it incorporates integrated VCOs, loop filters, as well as varactor diodes in a low-profile, 24-pin TSSOP that measures less than 150 square mm in area. In addition, it only requires four external passive components and consumes a typical current of only 18 mA at 3 VDC.
