DESCRIPTION
The BSFZ-series tuners are designed for reception of modulated digital data streams. These tuners can be used for reception of digital video and data streams.
The first Local Oscillator is Phase-Locked Loop tuned using a 3-wire or I2C-bus serial data bus. The second Local Oscillator in the I/Q Demodulator is controlled by a SAW resonator or an analog voltage depending on model. A prescaler is provided on the I/Q conversion oscillator output in some models for complete control of the conversion process.
The power supply is 5 V and 29 V.
