AK1548 Datasheet 8ghz Low Noise Integer-n Frequency Synthesizer

Manufacturer: AKM (Asahi Kasei Microdevices)

Overview: [AK1548] AK1548 8GHz Low Noise Integer-N Frequency Synthesizer 1. Overview The AK1548 is an Integer-N PLL (Phase Locked Loop) frequency synthesizer, covering a wide range of frequency from 1GHz to 8GHz. Consisting of a highly accurate charge pump, a reference divider, a programmable divider and a dual-modulus prescaler (P/P+1), this product provides high performance, very low Phase Noise and small footprints. An ideal PLL can be achieved by bining the AK1548 with the external loop filter and VCO (Voltage Controlled Oscillator). Access to the registers is controlled via a 3-wire serial interface. The operating supply voltage is from 2.7V to 3.3V, and the charge pump circuit and the serial interface can be driven by individual supply voltage. 2.
