NTE7108 Integrated Circuit 1.3GHz Phase Locked Loop w/I2C Bus
Description: The NTE7108 is an integrated circuit in an 18-Lead DIP type package and when used in combination with a VCO (tuner), comprises a digital programmable phase-locked loop (PLL) for television devices designed to use the PLL frequency synthesis tuning principle. The PLL provides a crystal-stable frequency for tuner oscillators between 16 1300MHz in the 62.5kHz raster. By including an external prescaler 1/2, the component can also be used for synthesizing applications of up to 2.4GHz (e.g. satellite receivers). As a result, the resolution is doubled to 125kHz. The tuning process is controlled via an I2C bus by the microprocessor.
