Abstract

A programmable digitally controlled oscillator (DCO) core is mapped on an Altera MAX9400 CPLD that can be used for clock recovery circuit of a 2.4 - 19.2 Kb/sec Gaussian Minimum Shift Keying (GMSK) demodulator. This architecture is suitable for digital wireless transceivers that use different bands for transmit and receive modes, such as SM and DECT. Linearity and phase noise of the DCO is analyzed at different oscillation frequencies. Thermal drift and power supply level sensitivity is characterized. This architecture can be used for higher frequencies using faster FPGA devices or by implementing it on a deep-submicron process.
