AK2365A - FM IF Detector

Datasheet Summary

Description

2nd-mixer to convert the input signal down to 450kHz.

The circuit composed of AGC and BPF, where the desired signal is amplified and spurious components included in the signal from the 2nd-mixer are eliminated.

The circuit to output filtered signal by AGC+BPF.

Features

  • The AK2365A includes 2nd-Mixer, AGC+BPF, PLL FM detector, noise squelch, and RSSI circuit. This device can eliminate E to J type ceramic filters, quadrature discriminator, and other external components.
  • Low operating voltage: VDD = 2.6 to 5.5 V.
  • Wide operating temperature: Ta = -40 to 85 C.
  • High sensitivity: -102dBm at 12dB SINAD.
  • De-emphasis + BPF.
  • Built-in PGA and 2nd Mixer.
  • Local frequency: 45.9MHz, 50.4MHz, 57.6MHz (Triple of 15.3, 16.8 and.
