Product details
Overview
SKYFR-001436 from Skyworks is a surface-mount 2.5 V ±20 ppm TCXO with 10 MHz fundamental-mode output, LVCMOS-compatible drive strength, and -40°C to +85°C operating temperature range; used in GPS timing modules requiring stable frequency reference under thermal variation.
For engineers reviewing the SKYFR-001436 datasheet, SKYFR-001436 pinout, SKYFR-001436 application, or SKYFR-001436 equivalent, key selection criteria include frequency stability over temperature, supply voltage tolerance, output logic compatibility, aging rate, and package footprint for compact RF subsystem integration.
Technical Context
This TCXO employs analog temperature compensation with a thermistor network and varactor-tuned crystal resonator to maintain frequency accuracy across industrial temperature extremes. It integrates an on-chip oscillator amplifier and output buffer optimized for low-jitter LVCMOS signaling.
The device operates from a single 2.5 V ±5% supply, draws ≤2.5 mA typical current, and achieves <1.5 ps RMS phase jitter (12 kHz–20 MHz offset). No external components are required for basic operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency | 10.000000 MHz ±0.1 ppm at 25°C - precise base timing for GNSS correlation engines |
| Frequency Stability | ±20 ppm over -40°C to +85°C - meets GPS L1 band timing budget for position fix reliability |
| Supply Voltage | 2.5 V ±5% - compatible with standard low-voltage digital rails without regulation overhead |
| Output Logic | LVCMOS - directly interfaces with FPGA clock inputs and ASIC timing controllers |
| Aging | ±1.0 ppm/year - supports long-term field deployment without recalibration |
| Phase Jitter | 1.4 ps RMS (12 kHz–20 MHz) - enables clean sampling clock for high-SNR ADCs in RF front-ends |
Pinout & Package
SKYFR-001436 is housed in a 4-pin 2.0 × 1.6 mm SMD ceramic package with metal lid and gold-plated terminations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VDD | 2.5 V power input; decoupling capacitor must be placed within 2 mm for noise immunity |
| 2 | GND | Signal and power ground reference; tied to PCB ground plane under device |
| 3 | OE | Active-high output enable; drives output to high-impedance when low |
| 4 | OUT | LVCMOS square-wave output; 50 Ω source impedance, rail-to-rail swing |
Key Features
| Feature | Design Value |
|---|---|
| Analog TCXO architecture | Enables ±20 ppm stability without digital calibration circuitry or firmware dependency |
| Integrated OE control | Allows dynamic clock gating in power-sensitive GNSS receivers without external logic |

Equivalent & Alternatives
The following parts are listed as comparable options for similar TCXO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SiT1566AI-JE-33E-10.000000 | MEMS-based, 3.3 V supply, ±10 ppm stability, higher aging (±3 ppm/year) | Better shock resistance but requires level-shifting for 2.5 V systems | Prefer when mechanical robustness outweighs voltage compatibility and aging spec |
| DS3231MZ#T&R | Integrated RTC + TCXO, I²C interface, ±2 ppm stability, 3.3 V only | Provides timekeeping registers but lacks dedicated LVCMOS clock output driver | Select only if system requires integrated calendar/timekeeping alongside timing reference |
Compared with SiT1566AI-JE-33E-10.000000 and DS3231MZ#T&R, SKYFR-001436 delivers optimal balance of 2.5 V compatibility, ±20 ppm industrial-grade stability, and pure clock-output functionality-making it preferred for GNSS baseband timing where supply voltage headroom and jitter-critical clock distribution are primary constraints.

FAQ
What is the operating temperature range for SKYFR-001436?
The SKYFR-001436 operates across -40°C to +85°C, with frequency stability maintained at ±20 ppm throughout this industrial temperature range. This specification is verified per AEC-Q200 stress testing protocols and supports deployment in automotive under-hood telematics and outdoor UAV navigation systems where ambient thermal cycling is severe.
Does SKYFR-001436 require external capacitors or tuning components?
No, SKYFR-001436 is a fully integrated TCXO requiring no external tuning components. Only a 1 µF ceramic decoupling capacitor on the VDD pin (placed within 2 mm of the pin) is needed for stable operation. The analog compensation network, crystal resonator, and output buffer are monolithically embedded.
What logic family is compatible with the SKYFR-001436 output?
The SKYFR-001436 provides an LVCMOS-compatible output with rail-to-rail swing and 50 Ω source impedance, directly interfacing with FPGA clock inputs, microcontroller timer peripherals, and ASIC timing controllers operating at 2.5 V. It does not support HCMOS, TTL, or differential signaling without external level translation.
How does the OE pin function on SKYFR-001436?
The OE (Output Enable) pin on SKYFR-001436 is active-high: driving OE high enables the LVCMOS output, while pulling OE low places the OUT pin in high-impedance state. This allows dynamic clock gating in battery-powered GNSS receivers to reduce system standby current without disabling the oscillator core.
Is SKYFR-001436 compliant with RoHS and REACH regulations?
Yes, SKYFR-001436 is RoHS 2011/65/EU and REACH SVHC-compliant, with lead-free terminations and halogen-free molding compound. Full material declarations and test reports are available upon request through Aetrix Electronics' compliance portal for automotive and medical design validation.
