Decoding YXC's OT8JI-111-50M: A Precision and Stable Oscillator

In the vast ocean of electronic design, the clock signal is the heart of the system. Today, we turn our attention to a standout product from YXC (Yangxing Technology)-the OT8JI-111-50M, an active crystal oscillator that strikes an exquisite balance between performance and cost.

Key Specifications at a Glance

The table below summarizes its critical parameters for quick reference.

Parameter	Specification
Brand	YXC (Yangxing Technology)
Frequency	50MHz
Supply Voltage	1.8V ~ 3.3V
Temperature Stability	±10ppm
Operating Temperature	-40℃ ~ +85℃
Output Mode	CMOS
Package	SMD7050-4P (7.0 x 5.0mm)

The standout feature of this oscillator is its **wide voltage range** (1.8V–3.3V), which allows compatibility with multiple logic levels including 1.8V, 2.5V, and 3.3V, greatly enhancing design flexibility. Additionally, it incorporates an industrial-grade temperature range (-40℃ to +85℃) and a fully sealed SMD package, ensuring reliable operation in demanding environments.

 Frequently Asked Questions (Q&A)

Q1: What does "temperature stability of ±10ppm" mean for the OT8JI-111-50M? Why do some datasheets show ±20ppm?**

A: ±10ppm refers to the maximum allowable frequency deviation from the nominal value across the specified temperature range. Some materials may indicate ±20ppm, which likely refers to **frequency stability**-a broader metric that accounts for additional factors such as voltage and load variations. In short, ±10ppm highlights its excellent temperature drift characteristics, while ±20ppm represents a more comprehensive stability indicator. Together, they ensure frequency accuracy from different perspectives.

Q2: Is there a replacement or equivalent model for this oscillator?

A: Yes. According to available documentation, the obsolete part number for the OT8JI-111-50M is OT705050MJBA4SL, and the two are fully interchangeable.

Applications and Advantages

With its high precision and wide-voltage capability, the OT8JI-111-50M is ideally suited for applications that demand stringent timing performance, such as industrial control, communication equipment, and IoT modules. Its built-in CMOS output can directly drive digital logic circuits, simplifying peripheral design. Moreover, in volume purchases, its cost advantage is notable-for example, at quantities of 1,000 pieces, the unit price can be as low as approximately 1.87 RMB, offering exceptional value for money.

In summary, YXC's OT8JI-111-50M is a clock solution that combines performance, reliability, and cost-effectiveness-making it a trustworthy choice for electronic engineers.
