Description

The SA647 is a low-voltage high performance monolithic digital system with high-speed RSSI incorporating a mixer, oscillator with buffered output, two limiting intermediate frequency amplifiers, fast logarithmic received signal strength indicator (RSSI), voltage regulator, RSSI op amp and power down pin. The SA647 is available in TSSOP (thin shrink small outline package).

The SA647 was designed for portable digital communication applications and will function down to 2.7V. The limiter amplifier has differential outputs with 2MHz small signal bandwidth. The RSSI output has access to the feedback pin. This enables the designer to level adjust the outputs or add filtering.

Features

• V_CC = 2.7 to 5.5V
• Low power receiver (5.3mA @ 3V)
• Power down mode (I_CC = 110µA)
• Fast RSSI rise and fall times
• Extended RSSI range with temperature compensation
• RSSI op amp
• 2MHz limiter small signal bandwidth
• Filter matching (1.5kW)
• Differential limiter output
• Oscillator buffer
• TSSOP-20 package

Applications

• NADC (North American Digital Cellular)
• Digital receiver systems
• Cellular radio
