BU2630FV 数据手册
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 : 0.2mA (typ), VDD = 3V FBlock diagram 3) 4) 5) 6) 7) 16-bit main counter. Internal 14-bit reference frequency counter. Unlock detection possible. Four output ports. (open drain) Control possible using 3-wire serial input. 91 Communication ICs FAbsolute maximum ratings (Ta = 25_C) BU2630F / BU2630FV FRecommended operating conditions (Ta = 25_C) FPin descriptions 92 Communication ICs FInput / output circuits BU2630F / BU2630FV 93 Communication ICs BU2630F / BU2630FV FElectrical characteristics (unless otherwise noted, Ta = 25_C, VDD = 3.0V, VSS = 0V) 94 Communication ICs FCircuit operation BU2630F / BU2630FV 95 Communication ICs BU2630F / BU2630FV Description of data (1) Programmable divider data: D0 X D15 (2) Reference frequency data: R0 X R13 (3) Output port control data : P-T (P-R) TON (RON) 1 : Open drain output ON (LO) 0 : Open drain output OFF (HI) (4) OFF transmission side (reception side) : Operation stopped F - T (F - R) pull-down : TPD (RPD) high-impedance, LD = OFF (5) PS Programmable device change : No. of divisions = 3 X 4095 96 Communication ICs (6) PL, PH, and PD pin control 0 0 : PLL operation 1 0 : Forced LO state 0 1 : Forced HI state 1 1 : Forced LO state (7) LD0, LD1, LD pin control (valid only on TX side) 0 0 : ON when unlocked (LO) 0 1 : Air pulse output 1 0 : Forced ON state (LO) 1 1 : Forced OFF state (HI) (8) Input (00) to test T0 and T1.
