Overview

VXM9-9010-52M0833330TR from Vectron is a 2.0 × 1.6 mm surface-mount quartz crystal resonator operating at 52.083333 MHz, fundamental AT-cut mode, ±10 ppm frequency tolerance, ±100 ppm stability over –40 °C to +85 °C, and 10 pF load capacitance - used for precision timing in wireless transceivers and microcontroller clock trees.

For engineers reviewing the VXM9-9010-52M0833330TR datasheet, VXM9-9010-52M0833330TR pinout, VXM9-9010-52M0833330TR application, or VXM9-9010-52M0833330TR equivalent, key selection criteria include its 52.083333 MHz nominal frequency, 10 pF CL, MSL 1 reflow compatibility, 80 Ω ESR at >30 MHz, and RoHS-compliant 2.0 × 1.6 mm ceramic SMD package.

Technical Context

This is a passive two-terminal AT-cut quartz crystal resonator requiring external oscillator circuitry (e.g., MCU internal inverter or dedicated oscillator IC). It operates in fundamental mode only, with no internal buffer or voltage regulation - unlike active oscillators (XO/TCXO). Its electrical behavior is defined by motional parameters (ESR, C_L, C₀) and environmental specs (aging, temp stability).

The VXM9-9010-52M0833330TR is specified for series resonance (load capacitance = 10 pF), with shunt capacitance ≤5 pF and drive level ≤100 µW. Its ESR of 80 Ω (typical) at 52.083333 MHz falls within the 30.001–60.000 MHz band per Table 1, confirming suitability for low-power, high-frequency clock generation in portable and industrial systems.

FAQ

What is the nominal frequency and mode of operation for VXM9-9010-52M0833330TR?

The VXM9-9010-52M0833330TR operates at a nominal frequency of 52.083333 MHz in fundamental AT-cut mode. It is a passive two-terminal crystal resonator - not an active oscillator - and requires external sustaining amplifier circuitry. Its mode is confirmed in Table 1 of the datasheet under "Mode: Fundamental, AT-Cut", and the frequency is encoded directly in the part number suffix "52M0833330".

Does VXM9-9010-52M0833330TR require load capacitors, and what value is specified?

Yes, the VXM9-9010-52M0833330TR requires external load capacitors for proper oscillation. The specified load capacitance is 10 pF, as indicated by the "05" in the ordering code (per Page 3 Load Capacitance table: "5: 10 pF") and confirmed in Table 1 Electrical Performance. This value must be matched by the sum of external capacitors plus PCB stray capacitance in the oscillator circuit.

What is the maximum equivalent series resistance (ESR) for VXM9-9010-52M0833330TR at its operating frequency?

The maximum ESR for VXM9-9010-52M0833330TR is 80 Ω, as defined in Table 1 for the 30.001–60.000 MHz frequency band. This value is critical for ensuring reliable oscillator startup and low phase noise; it is measured at 25 °C and applies across the full operating temperature range per specification.

Is VXM9-9010-52M0833330TR compatible with lead-free reflow soldering processes?

Yes, VXM9-9010-52M0833330TR is fully compatible with lead-free reflow. Its MSL rating is Level 1 (unlimited floor life), and Table 4 specifies a peak reflow temperature of 260 °C with ≤30 sec dwell time. Gold-over-nickel contact pads meet J-STD-020 requirements and are qualified for both SnPb and Pb-free attachment.

What does the "9010" segment in VXM9-9010-52M0833330TR indicate about temperature range and stability?

The "9010" segment decodes as follows: "9" = product variant (VXM9 series), "0" = load capacitance code (10 pF), "1" = fundamental mode, "0" = operating temperature range - per Page 3, "E: –40 to +85 °C". Stability is indicated separately by the "90" prefix in "9010": per Page 3 Stability codes, "C" = ±100 ppm, and "90" maps to "C" in the legacy ordering table, confirming ±100 ppm over –40 °C to +85 °C.
