Product details
Overview
SA606DK/01,112 from NXP Semiconductors is a low-voltage monolithic FM IF system integrating mixer/oscillator, dual limiting IF amplifiers, quadrature detector, logarithmic RSSI, voltage regulator, and rail-to-rail audio/RSSI op amps. It operates down to 2.7 V, delivers 17 dB mixer conversion gain at 45 MHz, provides 102 dB total IF/limiter gain, and supports RF input up to 150 MHz - enabling portable cellular radio and cordless phone receivers.
For engineers reviewing the SA606DK/01,112 datasheet, SA606DK/01,112 pinout, SA606DK/01,112 application, or SA606DK/01,112 equivalent, this page delivers verified functional identity, SSOP20 package mapping, validated 20-pin terminal roles, confirmed 90 dB RSSI dynamic range, and two field-validated alternative parts for FM IF receiver design.
Technical Context
The SA606DK/01,112 implements a Gilbert-cell mixer with integrated oscillator capable of >150 MHz operation using LC or crystal configurations, and features a two-stage IF chain: first-stage IF amplifier (43 dB gain, 5.5 MHz BW) followed by limiter (60 dB gain, 4.5 MHz BW), optimized for 455 kHz ceramic filters with 1.5 kΩ input/output impedance.
Its quadrature detector uses internal IF signal and externally phase-shifted IF to drive a multiplier cell; demodulated audio feeds a configurable rail-to-rail op amp, while the temperature-compensated logarithmic RSSI delivers ≥90 dB dynamic range with ±1.5 dB variation across −40 °C to +85 °C ambient.

Equivalent & Alternatives
The following parts are listed as comparable options for similar FM IF receiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SA605D/01,112 | Lower integration: lacks quadrature detector, RSSI, audio op amp, and voltage regulator; requires external IF limiting and demodulation | Suitable only for first IF or mixer-only functions; not drop-in for SA606DK/01,112's complete IF chain role | Select when designing custom IF architecture with discrete demodulator or needing higher mixer IP3 (−12 dBm vs −9 dBm) |
| MC3362P | Higher supply current (6.5 mA), no integrated RSSI op amp, fixed 455 kHz IF center, no rail-to-rail outputs | Legacy automotive/industrial FM IF part; lacks portable low-voltage optimization and modern RSSI calibration | Choose for cost-sensitive legacy replacements where 3.5 mA operation and 90 dB RSSI range are not required |
