GP214D Datasheet, PDF (1/15 Pages) List of Unclassifed Manufacturers – 1.4GHz DUAL PLL

GP214D
1.4GHz DUAL PLL
DESCRIPTION
The GP214D is a dual frequency synthesizer designed for RF operation up to 1.4GHz. The device
contains prescalers, programmable reference, and feedback frequency dividers, phase detectors, and
charge pumps necessary for the precision control of dual VCO loops. Data transfer is made via a simple
serial data interface. The GP214D is fabricated using advanced CMOS process and available in a 16-pin
TSSOP plastic package with 0.65mm pitch.
