By Dr. KH MunIn 2021, Epson announced they will no longer be manufacturing their MA-306 crystal [1]. The MA-306 package reached end-of-life in 2021, and the SXT834’s matching 8.0×3.8mm footprint and 8–54 MHz range make it a direct fit for the lower-frequency, height-constrained designs the MA-306 served. While parts going obsolete isn’t a new concept,…

By Dr. KH MunMicro BNC connectors are designed for the HD & UHD Broadcast, Telecom, and HD CCTV markets where applications require high performance in a high-density package. Suntsu’s HD (High Density) BNC connectors deliver 75Ω, enhancing both electrical and mechanical performance. These connectors not only have 4x the density, but the form factor is…

By Dr. KH Mun5G communication is the latest and greatest in wireless network technology. Applications that utilize this infrastructure, such as small cells, base stations, and Wifi-6/6E, require the use of high-precision TCXO’s (Temperature-Compensated Crystal Oscillators) to achieve high-speed, high-capacity, and ultra-low latency performance requirements. Stable clocking is fundamental to 5G network synchronization, and TCXOs…

By Dr. KH MunFirst introduced in 1996, the Universal Serial Bus, more commonly referred to as USB, is the most popular interconnect standard for communication, connection, and power supply. When the first USB was released, the maximum signaling rate was 12 Mb/s, but as speed requirements have increased, updated USB generations were released to accommodate…

By Dr. KH MunThe Bayonet Neil-Concelman (BNC) connector is a radio frequency connector used with coaxial cables. These connectors were originally designed for military applications and were used in early computer networks. Today, BNC connectors are widely used in telecommunication and broadcast applications. Suntsu’s BNC connectors are industrial grade with 50 Ohm and 75 Ohm…

By Dr. KH MunRJ45 connectors are widely used modular interconnection devices that transmit both signals and electrical power to the devices they are connecting to via cables. Suntsu is now offering both magnetic and non-magnetic RJ45 Jacks to accommodate a vast array of market applications. Our magnetic RJ45 jack line includes options for 10/100/1000 Base-T,…

By Dr. KH MunSuntsu is proud to announce that we have added power inductors to our product offering, as they are an essential component of voltage regulator topology [2]. Suntsu’s SMD power inductors are manufactured with a magnetic shielded structure. This helps them achieve excellent resistance to EMI (Electro-Magnetic Interference), low DCR, and high rated…

By Dr. KH MunUnlike traditional oscillators, which derive their frequency from a mechanical resonator such as a quartz crystal or MEMS element, Suntsu’s resonator-free silicon oscillators generate the clock entirely from on-chip circuitry — delivering a highly reliable clock in harsh, high-vibration environments without any quartz or MEMS resonator [1] [2]. The built-in frequency synthesis…

By Dr. KH MunSmaller TCXO packages are used and sometimes required for many different applications, but there have been drawbacks to their small size. While the crystal blank can be produced in a small enough size, incorporating ICs inside the package meant sacrificing their aging performance and stability [2]. To solve this issue, Suntsu is…

By Dr. KH MunSuntsu’s new RTC (Real-Time Clock), SLR32CN-32.768K, has a built-in 32.768kHz TCXO with an I2C bus interface and provides ultra-low power consumption. The 32.768 kHz crystal is the long-standing RTC timekeeping standard — 2¹⁵ Hz divides cleanly to a one-second tick — and pairing it with an I²C interface and microamp-level current draw…

By Dr. KH Mun Watch Crystal Shortages? The world’s most popular tuning fork watch crystal has been the 3.2mm x 1.5mm package for a long time. Suntsu’s equivalent watch crystal, the SWS312 series, has been popular among our customers! Unfortunately, this part is becoming harder and harder to find in the marketplace, and lead times…
