SA616 Low-voltage high performance mixer FM IF system Rev. 5 24 July 2012 Product data sheet 1. General description The SA616 is a low-voltage high performance 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 SA616 is available in SSOP20 and HVQFN20 packages. The SA616 was designed for portable communication applications and will function down to 2.7 V. The RF section is similar to the famous SA615. The audio and RSSI outputs have amplifiers with access to the feedback path. This enables the designer to adjust the output levels or add filtering. 2. Features and benefits Low power consumption: 3.5 mA typical at 3 V Mixer input to >150 MHz Mixer conversion power gain of 17 dB at 45 MHz XTAL oscillator effective to 150 MHz (LC oscillator or external oscillator can be used at higher frequencies) 102 dB of IF amp/limiter gain 2 MHz IF amp/limiter small signal bandwidth Temperature compensated logarithmic RSSI with a 80 dB dynamic range Low external component count suitable for crystal/ceramic/LC filters Excellent sensitivity: 0.31 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 SA616 meets cellular radio specifications Audio output internal op amp RSSI output internal op amp Internal op amps with rail-to-rail outputs ESD protection exceeds 2000 V HBM per JESD22-A114 and 1000 V CDM per JESD22-C101 Latch-up testing is done to JEDEC Standard JESD78 Class II, Level B 3.
