Oscillators — TDE Timing Devices Europe
Category 02 · Oscillators

The crystal and the circuit — in one part.

An oscillator integrates the resonator, the sustaining amplifier and the output stage into a single sealed package. No load-cap matching, no layout tuning — a clean clock signal, the moment you apply power.

Three Families

XO, TCXO, VC-TCXO. Pick by stability.

All three integrate the resonator — what separates them is how tightly they hold frequency over temperature, and whether you can pull it. TDE stocks every family across the partner range.

Family A · XO

Clock Oscillator

Simple packaged oscillator (SPXO)

The workhorse clock. A fixed-frequency oscillator with a clean CMOS output — the standard reference for microcontrollers, FPGAs, USB and Ethernet. Drop-in, no external parts.

±20–100 ppmCMOS 1–200 MHzMCU / FPGA
Family B · TCXO

Temp-Compensated

Stable across the full temp range

When drift is the enemy. Internal compensation holds frequency tight from −40 to +85 °C — the reference for GNSS, cellular, radio and any timing-critical link.

±0.5–2.5 ppmClipped Sine GNSS / 5G
Family C · VC-TCXO

Voltage-Controlled TCXO

Temp-compensated — and pullable

Compensated stability plus a control-voltage input that pulls the frequency within a defined range. The modern reference for disciplined oscillators, PLL loops and synchronisation to GNSS or a network clock.

The Parameters That Matter

Six numbers decide the part.

An oscillator hides the resonator circuit — but these six lines still drive the design-in, from supply rail to phase jitter budget.

Parameter
Typical range
Why it matters
Output frequency
1 – 200 MHz
Many parts are factory-programmable to your exact frequency.
Frequency stability
±0.5 – ±100 ppm
Total budget over temp, ageing and voltage. TCXO and VC-TCXO are tightest.
Output logic
CMOS · Clipped Sine · LVDS
Must match the receiving input. LVDS for high-speed differential.
Supply voltage
1.8 / 2.5 / 3.3 V
Pick the rail your board already provides.
Phase jitter
< 1 ps RMS (typ.)
Critical for SerDes, PCIe and RF — the cleaner, the better.
Current consumption
< 1 mA – 25 mA
Higher with frequency and load. Low-power options for battery designs.
Output Logic

Match the waveform to the receiver.

The output stage decides board-level compatibility. CMOS for general logic, differential types for clean high-speed links.

Selection Guide

Three steps to the right oscillator.

01

Stability first

Define your frequency budget over temperature. A relaxed XO for general logic, a TCXO when an RF or GNSS link depends on it — a VC-TCXO when it also has to be steered.

→ See the three families above
02

Output & supply

Match the output logic to the receiving input, and pick the supply rail your board already runs. Mind the phase-jitter budget for SerDes.

→ See output logic & spec table
03

Package & second source

Choose the footprint, then secure a pin-compatible alternative. We'll show equivalents across all three manufacturers.
