• Manufacturer Part Number: tda8751t
• Description: Qpsk Receiver
• Manufacturer: NXP Semiconductors

Philips Semiconductors
Notes
1. The frequency range of the receiver is 44 to 130 MHz. The local oscillator (LO) operates at twice the output
2. Crystal oscillator. The crystal oscillator uses a 4, 2 or 1 MHz crystal in series with a capacitor. The crystal is parallel
