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 synthesiz ing 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.

Features:

• Low Current Consumption

• Message Transmission Via I2C Bus

• 4 Software–Controlled Outputs

• Cost–Effective and Space–Saving Design

• Prescaler Output Frequency is Free from Interference Radiation
