General description

The SA676 is a low-voltage monolithic FM IF system incorporating a mixer/oscillator, two limiting intermediate frequency amplifiers, quadrature detector, logarithmic received signal strength indicator (RSSI), voltage regulator and audio and RSSI op amps. The SA676 is available in a 20-pin SSOP (shrink small outline package).

The SA676 was designed for cordless telephone applications in which efficient and economic integrated solutions are required and yet high performance is desirable. Although the product is not targeted to meet the stringent specifications of high performance cellular equipment, it will exceed the needs for analog cordless phones. The minimal amount of external components and absence of any external adjustments makes for a very economical solution.

Features

  • Low power consumption: 3.5mA typical at 3V
  • Mixer input to >100MHz
  • Mixer conversion power gain of 17dB at 45MHz
  • XTAL oscillator effective to 100MHz (L.C. oscillator or external oscillator can be used at higher frequencies)
  • 102dB of IF Amp/Limiter gain
  • 2MHz IF amp/limiter small signal bandwidth
  • Temperature compensated logarithmic Received Signal Strength Indicator (RSSI) with a 70dB dynamic range
  • Low external component count; suitable for crystal/ceramic/LC filters
  • Audio output internal op amp
  • RSSI output internal op amp
  • Internal op amps with rail-to-rail outputs
  • ESD protection:
    Human Body Model 2kV
    Robot Model 200V
