DESCRIPTION

· The BU2630F/BU2630FV are CMOS LSI with an internal dual PLL synthesizer.

· VCOs for transmission and reception can be controlled independently.

· Reference frequency and main counter settings can be programmed separately.

· Designed for cordless telephones and communications equipment worldwide.

FEATURES

· Operates up to 80MHz (VDD = 2.5).

· Low current dissipation: Dual-system operation: 2.2mA (typ), Single-system operation: 1.2mA (typ), Non-operating state: 0.2mA (typ) at VDD = 3V.

· 16-bit main counter.

· Internal 14-bit reference frequency counter.

· Unlock detection capability.

· Four open-drain output ports.

· Controlled via 3-wire serial input.

APPLICATIONS

· Cordless telephones.

· Amateur short wave radios.

· Industrial transceivers.

· VHF/UHF frequency generators.
