10 / 24 page 1999 Aug 20 10 Philips Semiconductors Product specification QPSK receiver TDA8051 Notes 1. The frequency range of the receiver is 44 to 130 MHz. The local oscillator (LO) operates at twice the output frequency (88 to 260 MHz). Frequency control by varicap diodes allows a variation over one octave. 2. Crystal oscillator. The crystal oscillator uses a 4, 2 or 1 MHz crystal in series with a capacitor. The crystal is parallel resonant with load capacitance of 18 to 20 pF. Connection to VCC is preferred but can also be to GND.
