SA616
Low-voltage high performance mixer FM IF system

1997 Nov 07
853-1676 18665
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 20-lead SSOP (shrink
small outline package).
The SA616 was designed for portable communication applications
and will function down to 2.7V. 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.
FEATURES
Low power consumption: 3.5mA typical at 3V
Mixer input to >150MHz
Mixer conversion power gain of 17dB at 45MHz
XTAL oscillator effective to 150MHz (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 80dB dynamic range
Low external component count; suitable for crystal/ceramic/LC
filters
Excellent sensitivity: 0.31V into 50 matching network for 12dB
SINAD (Signal to Noise and Distortion ratio) for 1kHz tone with RF
at 45MHz and IF at 455kHz
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: Human Body Model 2kV
Robot Model 200V
