SA676DK - Low-voltage mixer FM IF system

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.

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) SR00514 Figure 1. Pin Configuration.
  • 102dB of IF Amp/Limiter gain.
  • 2MHz IF amp/limiter small signal bandwidth.
  • Temperature compensated logarithmic Received Signal Strength Indicator (RSSI) with a 70dB dynami.

Philips Semiconductors Product specification Low-voltage mixer FM IF system SA676 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.
