| M I C of Crystek Corporation ROWAVE A Division CPLL58-2450-2450 0.582" x 0.800" SMD Features 2.450GHz Standard 3 Wire Interface Small layout 0.582" x 0.8" Applications Digital Radio Equipment Fixed Wireless Access Satellite Communications Systems Base Stations Personal Communications Systems Portable Radios Test Instruments Wireless Infrastructure The CPLL58 is a complete PLL/Synthesizer needing only an external frequency reference and supply voltages for the internal PLL (phase lock loop) and VCO (voltage controlled oscillator). The Crystek CPLL58 is programmed using a standard three line interface (Data, Clock and Load Enable). The CPLL58 family has been initially released to cover 1GHz to 5GHz in bands. It is housed in a compact 0.582-in. x 0.8-in. x 0.15-in. SMD package which saves board space. Typical phase noise at 4GHz is -90dBc/Hz at 10KHz offset with 0dBm minimum output power.

Latch Summary When using the CPLL58 family in a synthesizer application, all four 24 bit registers need to be written into after power-up. After writing all four latches the first time, subsequent frequency step changes can be accomplished by changing the N Counter Latch only. Specifications subject to change without notice.
