AK2365 - dPMR Filterless IF LSI

General Description

MIX AGC+BPF IFBUF Divider Limiter DISCRI LPF Noise AMP Noise Rectifier Comparator RSSI VIREF LDO Control Logic 2nd-mixer to convert the input signal down to 450kHz.

Key Features

  • The AK2365 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.
  • Built-in PGA and 2nd Mixer.
  • Local frequency: 45.9MHz, 50.4MHz, 57.6MHz (Triple of 15.3, 16.8 and 19.2MHz).
  • Buil.
