AK2364 - Two-way Radio Filterless FM Detector LSI

Datasheet Summary

Description

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

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 divide the signal from LOIN pin and supply BPF with CLK.

Features

  • The AK2364 includes 2nd-Mixer, AGC+BPF, PLL FM detector, noise squelch, and RSSI circuit. This device can eliminate D to G 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.
  • Hi sensitivity: -104dBm at 12dB SINAD.
  • Built-in 2nd Mixer.
  • Local frequency: 45.9MHz, 50.4MHz, 57.6MHz (Triple of 15.3, 16.8 and 19.2MHz).
  • Built-in progra.
