LMC568中文资料低功耗锁相环数据手册TI规格书

描述 Description

The LMC568 is an amplitude-linear phase-locked loop consisting of a linear VCO, fully balanced phase detectors, and a carrier detect output. LMCMOS technology is employed for high performance with low power consumption.The VCO has a linearized control range of ±30% to allow demodulation of FM and FSK signals. Carrier detect is indicated when the PLL is locked to an input signal greater than 26 mVrms. LMC568 applications include FM SCA and TV second audio program decoders, FSK data demodulators, and voice pagers.
