1. general description the sa676 is a low-voltage 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 sa676 is available in a 20-pin ssop (shrink small outline package). the sa676 was designed for cordless telephone applications in which efficient and economic integrated solutions are required and yet high performance is desirable. although the product is not targeted to meet the stringent specifications of high performance cellular equ ipment, it will exceed the needs for analog cordless phones. the minimal amount of external components and absence of any external adjustments makes for a very economical solution. 2. features and benefits ? low power consumption: 3.5 ma typical at 3 v ? mixer input to > 100 mhz ? mixer conversion power gain of 17 db at 45 mhz ? xtal oscillator effective to 100 mhz (lc oscillator or external oscillator can be used at higher frequencies) ? 102 db of if amplifier/limiter gain ? 2 mhz if amp/limiter small signal bandwidth ? temperature compensated logarithmic receiv ed signal strength indicator (rssi) with a 70 db dynamic range ? low external component count; suitab le for crystal/ceramic/lc filters ? audio output internal op amp ? rssi output internal op amp ? internal op amps wit h rail-to-rail outputs ? esd protection exceeds 2000 v hbm per jesd22-a114 and 1000 v cdm per jesd22-c101 ? latch-up testing is done to jedec standard jesd78 class ii, level b 3. applications ? cordless telephones sa676 low-voltage mixer fm if system rev. 3 ? 19 july 2012 product data sheet

(2) the smallest rssi voltage (i.e., when no rf input is present and the input is terminated) is a measure of the quality of the layout and design. if the lowest rssi voltage is 500 mv or higher, it means the receiver is in regenerative mode. in that case, the receiver sensit ivity will be worse than expected. (3) the c-message and de-emphasis filter combinati on has a peak gain of 10 db for accurate measurements. without the gain, the measurement s may be affected by the noise of the scope and hp339a analyzer. the de-emphasis filter has a fixed ? 6 db/octave slope between 300 hz and 3khz.
