SA615 High performance low power mixer FM IF system Rev. 4 — 14 November 2014 Product data sheet 1. General description The SA615 is a high performance monolithic low-power FM IF system incorporating a mixer/oscillator, two limiting intermediate frequency amplifiers, quadrature detector, muting, logarithmic Received Signal Strength Indicator (RSSI), and voltage regulator. The SA615 combines the functions of NXP Semiconductors SA602A and SA604A, but features a higher mixer input intercept point, higher IF bandwidth (25 MHz) and temperature compensated RSSI and limiters permitting higher performance application. The SA615 is available in 20-lead SO (surface-mounted miniature package) and 20-lead SSOP (shrink small outline package). The SA605 and SA615 are functionally the same device types. The difference between the two devices lies in the guaranteed specifications. The SA615 has a higher ICC, lower input third-order intercept point, lower conversion mixer gain, lower limiter gain, lower AM rejection, lower SINAD, higher THD, and higher RSSI error than the SA615. Both the SA605 and SA615 devices meet the EIA specifications for AMPS and TACS cellular radio applications. 2. Features and benefits  Low power consumption: 5.7 mA typical at 6 V  Mixer input to >500 MHz  Mixer conversion power gain of 13 dB at 45 MHz  Mixer noise figure of 4.6 dB at 45 MHz  XTAL oscillator effective to 150 MHz (L/C oscillator to 1 GHz local oscillator can be injected)  102 dB of IF amplifier/limiter gain  25 MHz limiter small signal bandwidth  Temperature-compensated logarithmic Received Signal Strength Indicator (RSSI) with a dynamic range in excess of 90 dB  Two audio outputs — muted and unmuted  Low external component count; suitable for crystal/ceramic/LC filters  Excellent sensitivity: 0.22 V into 50  matching network for 12 dB SINAD (Signal-to-Noise-and-Distortion ratio) for 1 kHz tone with RF at 45 MHz and IF at 455 kHz  SA615 meets cellular radio specifications  ESD hardened NXP Semiconductors SA615 High performance low power mixer FM IF system 3.
