SA614A - Low power FM IF system

Datasheet Summary

Description

The SA614A is an improved monolithic low-power FM IF system.

It incorporates two limiting intermediate frequency amplifiers, quadrature detector, muting, logarithmic received signal strength indicator, and voltage regulator.

Features

  • Low power consumption: 3.3 mA typical.
  • Temperature compensated logarithmic RSSI with a 90 dB dynamic range.
  • Two audio outputs - muted and unmuted.
  • Low external component count; suitable for crystal/ceramic filters.
  • Excellent sensitivity: 1.5 V across inputs pins (0.22 V into 50  matching network) for 12 dB SINAD (SIgnal-to-Noise-And-Distortion ratio) for 1 kHz tone with RF at 45 MHz and IF at 455 kHz.
  • SA614A meets cellular radio specifications 3.

SA614A Low power FM IF system Rev. 4 — 14 February 2014 Product data sheet 1. General description The SA614A is an improved monolithic low-power FM IF system. It incorporates two limiting intermediate frequency amplifiers, quadrature detector, muting, logarithmic received signal strength indicator, and voltage regulator. The SA614A features higher IF bandwidth (25 MHz) and temperature compensated RSSI and limiters permitting higher performance application compared with the SA604. The SA614A is available in a SO (surface-mounted miniature) package. 2. Features and benefits  Low power consumption: 3.
