Communication ICs Dual PLL frequency synthesizer BU2630F / BU2630FV The BU2630F / BU2630FV are a CMOS LSI with an internal dual PLL synthesizer. VCOs for transmission and reception can be controlled independently, and the reference frequency and main counter settings can also be programmed separately. This product is designed for applications involving cordless telephones and communications equipment worldwide. FApplications Cordless telephones, amateur short wave radios, industrial transceivers, VHF / UHF frequency generators, and others FFeatures 1) Operation possible at up to 80MHz (VDD = 2.5). 2) Low current dissipation Dual-system operation : 2.2mA (typ), VDD = 3V Single-system operation : 1.2mA (typ), VDD = 3V Non-operating state : 0.
