SA614A
Low power FM IF system
2
1997 Nov 07
853-0594 18663
DESCRIPTION
The SA614A is an improved monolithic low-power FM IF system
incorporating two limiting intermediate frequency amplifiers,
quadrature detector, muting, logarithmic received signal strength
indicator, and voltage regulator. The SA614A features higher IF
bandwidth (25MHz) and temperature compensated RSSI and
limiters permitting higher performance application compared with the
SA604. The SA614A is available in a 16-lead dual-in-line plastic
and 16-lead SO (surface-mounted miniature) package.
FEATURES
Low power consumption: 3.3mA typical
Temperature compensated logarithmic Received Signal Strength
Indicator (RSSI) with a dynamic range in excess of 90dB
Two audio outputs - muted and unmuted
Low external component count; suitable for crystal/ceramic filters
Excellent sensitivity: 1.5V across input pins (0.22V into 50
matching network) for 12dB SINAD (Signal to Noise and Distortion
ratio) at 455kHz
SA614A meets cellular radio specifications
