Texas Instruments introduces a clock synthesizer and jitter cleaner for applications such as 2.5G/3G wireless basestations, data communications, medical imaging and test and measurement. The CDCM7005 provides stable frequencies for signal-chain devices such as A/D converters (ADC), D/A converters (DAC), digital upconverters (DUC) and digital downconverters (DDC). It offers phase noise of – 219 dBc/Hz (PLL figure of merit) and phase jitter performance of 162 fs (LVPECL) and 232 fs (LVCMOS), and maximum output skew of 20 ps. This performance allows data converters such as ADCs to be undersampled at higher input frequencies while delivering high signal-to-noise ratio.
