SA604AD01 Datasheet, PDF (2/13 Pages) NXP Semiconductors – High performance low power FM IF system
Philips Semiconductors
High performance low power FM IF system
Product specification
SA604A
DESCRIPTION
The SA604A 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 SA604A features higher IF
bandwidth (25MHz) and temperature compensated RSSI and
limiters permitting higher performance application compared with the
SA604. The SA604A is available in a 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: 1.5µV across input pins (0.22µV into 50Ω
matching network) for 12dB SINAD (Signal to Noise and Distortion
ratio) at 455kHz
• SA604A meets cellular radio specifications
