Low-voltage high performance mixer FM IF system
Product specification
SA616
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: 0.31µV into 50Ω 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
