Product details
Overview
OM13312,598 from NXP Semiconductors is a SA636DK/02 variant - a low-voltage (2.7–5.5 V) FM IF system IC integrating mixer/oscillator, dual limiting IF amplifiers, quadrature detector, temperature-compensated logarithmic RSSI (90 dB dynamic range), wideband data output (≥600 kHz), and power-down control. It operates at 10.7 MHz IF with 330 Ω impedance matching and targets DECT and portable digital cordless telephony.
For engineers reviewing the OM13312,598 datasheet, OM13312,598 pinout, OM13312,598 application, or OM13312,598 equivalent, key selection criteria include its screened RSSI output voltage (0.15–0.45 V at −118 dBm IF), SSOP20 package compatibility, 6.5 mA typical supply current at 3 V, and support for external LO injection up to 1 GHz.
Technical Context
The OM13312,598 implements a single-conversion FM receiver architecture with a Gilbert-cell mixer (11 dB conversion gain, 12 dB noise figure at 240 MHz), 92 dB total IF/limiter gain, and 25 MHz small-signal limiter bandwidth optimized for 10.7 MHz ceramic filters. Its RSSI circuit includes an internal rail-to-rail op amp with feedback pin (RSSI_FEEDBACK) enabling external gain adjustment or filtering.
Power management is handled via CMOS/TTL-compatible POWER_DOWN_CTRL (active HIGH), reducing ICC to 200 µA in standby. The device supports both crystal (≤150 MHz) and LC (≤1 GHz) oscillator configurations and delivers fast RSSI rise/fall times (1.1–1.2 µs / 2.0–7.3 µs) across input signal levels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7 V to 5.5 V - enables direct battery operation in portable devices without LDO regulation. |
| Supply Current | 6.5 mA typical at 3 V - defines power budget for handheld receivers with continuous RX mode. |
| RSSI Dynamic Range | >90 dB - supports detection of weak signals (−118 dBm) and strong interferers (−10 dBm) within same system. |
| Data Output Bandwidth | ≥600 kHz - sufficient for DECT 1.88–1.90 GHz FSK data demodulation without external baseband filtering. |
| Mixer Input Frequency | Up to 500 MHz - allows direct RF input for VHF/UHF receivers without pre-mixing stages. |
| IF Impedance Matching | 330 Ω - permits direct connection to standard 10.7 MHz ceramic filters without external matching networks. |
| Power-Down Current | 200 µA - reduces quiescent consumption during sleep intervals in burst-mode communication systems. |

| POWER_DOWN_CTRL (8) | Active-HIGH enable for power-down mode | Drives internal bias shutdown; logic-high (>0.7×VCC) disables core circuits, reducing ICC to 200 µA. |
| DATA_OUT (9) | Demodulated FM data output | Voltage-mode output with ≥600 kHz bandwidth; drives 100 kΩ load with 120–130 mV RMS level. |
| QUADRATURE_IN (10) | Quadrature detector reference input | Accepts AC-coupled 90° phase-shifted IF signal for coherent quadrature demodulation. |
| LIMITER_DECOUPL (12,13) | Limiter stage decoupling terminals | Dual 1.23 V DC-biased pins requiring local 100 nF capacitors to stabilize high-gain limiter stage. |
Key Features
| Feature | Design Value |
|---|---|
| Screened RSSI output | 0.15–0.45 V at −118 dBm IF level - ensures consistent AGC threshold across production units for DECT handset calibration. |
| Wideband data output | ≥600 kHz minimum bandwidth - supports high-data-rate FSK/ASK demodulation in DECT and wireless LAN receivers. |
| Low-power mixer architecture | 11 dB conversion gain and 12 dB noise figure at 240 MHz - achieves 0.54 µV sensitivity into 50 Ω for 12 dB SINAD. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FM IF demodulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SA636DK/01 | RSSI output un-screened: 0.2–0.5 V at −118 dBm IF vs. OM13312,598's 0.15–0.45 V range | Less stringent RSSI calibration required; suitable for non-DECT applications where AGC precision is relaxed | Select when RSSI tolerance >±0.15 V is acceptable and cost optimization is prioritized over factory screening. |
| SA636BS | HVQFN20 package (4×4×0.85 mm) vs. SSOP20; exposed DAP requires PCB thermal pad; identical electrical specs | Better thermal performance (Zth(j-a) = 40 K/W vs. 117 K/W) and smaller footprint for space-constrained designs | Select when board area is limited and thermal management via PCB vias is feasible; not drop-in compatible due to different pinout and package. |
Compared with SA636DK/01 and SA636BS, OM13312,598 provides tighter RSSI voltage screening for calibrated AGC in DECT handsets while retaining full SSOP20 compatibility - making it optimal for volume production where consistent RSSI linearity across temperature and unit variance is critical.

FAQ
What is the primary function of OM13312,598 in a receiver system?
OM13312,598 serves as a complete FM intermediate frequency (IF) signal processor, integrating mixer/oscillator, dual limiting IF amplifiers, quadrature detector, temperature-compensated RSSI, and wideband data output. It converts RF signals to baseband audio/data while providing real-time signal strength measurement - all within a single SSOP20 package.
How does the RSSI output of OM13312,598 differ from standard SA636 variants?
OM13312,598 is the SA636DK/02 variant, meaning its RSSI output voltage at −118 dBm IF level is factory-screened to 0.15–0.45 V. This tighter specification ensures consistent AGC behavior across units, unlike the broader 0.2–0.5 V range of SA636DK/01, making OM13312,598 ideal for DECT handset calibration.
Can OM13312,598 operate with an external local oscillator?
Yes, OM13312,598 supports external LO injection up to 1 GHz via the OSC_IN/OSC_OUT pins. Its internal oscillator also functions with crystal (≤150 MHz) or LC tank configurations, giving designers flexibility to optimize phase noise, power, and frequency agility based on system requirements.
What package type is used for OM13312,598 and what are its key mechanical features?
OM13312,598 uses the SSOP20 (SOT266-1) package: 20-lead shrink small outline with 4.4 mm body width, 0.65 mm lead pitch, and gull-wing leads. Its compact size and standard footprint enable high-density PCB layouts while maintaining compatibility with automated assembly processes.
Does OM13312,598 require external decoupling components, and if so, where?
Yes, OM13312,598 requires multiple local decoupling capacitors: 100 nF at RF_IN_DECOUPL (pin 2), two 100 nF caps at LIMITER_DECOUPL (pins 12 and 13), and 100 nF at IF_AMP_DECOUPL (pins 17 and 19). These stabilize high-gain RF and IF stages and prevent oscillation in sensitive receiver front-ends.
