DESCRIPTION
LMCMOS technology is employed for high performance with low power consumption. 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. Typical Application (100 kHz input frequency, refer to Notes to Typical Application) Figure 1. 8-Pin SOIC or PDIP See D or P Package 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
