详细说明
The DHL612 is an integrated frequency synthesizer with prescaler. It consists of a dual-modulus prescaler(64/65, 128/129), programmable P(11-bit) and S(7-bit) counter, programmable R(14-bit) counter, a phase frequency detector(PFD) and a charge pump(1.5mA, 6mA). A PLL can be completely implemented with external loop filter and VCO(voltage controlled oscillator).
Features:
Maximum 1.2GHz operation
Low supply current consumption (2.2mA@3V, 2.4mA@5V)
Wide supply voltage range (2.4V ~ 5.5V)
3-wire serial interface
Power-down mode
Lock detection
MB15E03SL compatible
