TEA5570 Datasheet (NXP) - AM/FM radio RF/IF

TEA5570, AM/FM radio RF/IF

TEA5570 The TEA5570 is a monolithic integrated radio circuit for use in portable receivers and clock radios.

The IC is also applicable to mains-fed AM and AM/FM receivers and car radio-receivers.

Apart from the AM/FM switch function the IC incorporates for AM a double balanced mixer, 'one-pin' osc
