PLL Clock Synthesizer Module - CKM151

General Description:

The CKM151 module generates a fixed-frequency clock. The CKM151 module utilizes a phase locked loop with a low-frequency reference clock to generate a high-frequency clock signal. The low-frequency reference clock for the phase frequency detector is selectable between an on-board 24 MHz crystal oscillator or a user-supplied external square-wave source(5 MHz to 300 MHz AC-coupled with minimum swing 800 mVpp). The selection of the reference clock can be done by simple hardware modification. An on-board LED lights up whenever a lock is achieved. With a power amplifier at the output stage, the CKM151 delivers a 8 dBm output through a SMA. The CKM151 module operates upon power-up by a 12V wall-mount AC adapter. The CKM151 is currently available in four versions: 2.0 GHz, 2.5 GHz, 3.0 GHz, and 4.0 GHz. When ordering, please specify the model and version number.
