Mingjiada Supply SiTime Clock Generators, Supply Real-Time Clock (RTC)

Shenzhen Mingjiada Electronics Co., Ltd. — Long-term supplier of the full range of [SiTime] clock generators, real-time clocks (RTCs) and other products. Our stock covers all mainstream models, and we support both small-batch samples and large-volume orders. Backed by an efficient logistics system, we ensure rapid product delivery.

I. Clock Generators
Details: SiTime clock generators feature four independent quarter-N PLLs, four inputs, up to 12 outputs, a wide frequency range from 200 kHz to 2.1 GHz, and a rich set of programmable functions within a compact QFN package.
Features:
Low integral jitter of 85 fs minimises bit error rates and enhances design margin
Consistently reliable start-up even at low temperatures and under other harsh environmental conditions
When used in conjunction with MEMS oscillators, quartz-related issues are eliminated, including jitter degradation, activity drop/frequency hopping and vibration sensitivity caused by noise coupling to the crystal interface
Models supplied by Mingjiada Electronics:
SiT95211 – Ultra-low jitter, four-channel phase-locked loop (PLL), programmable frequency, 12-output clock generator
SiT95210 – Low jitter, four-channel PLL, 4-output clock generator
SiT30100 – Four-output mobile clock generator with integrated MEMS resonator and temperature sensor
SiT95272 — 12-output clock generator with PCIe Gen 7 spread-spectrum clock
SiT95278 — 8-output clock generator supporting PCIe Gen 7 spread-spectrum clock

II. Real-Time Clock (RTC)
Details: SiTime’s real-time clock (RTC) and calendar devices offer dual I²C bus support, allowing access to two host devices, such as a CPU and a BMC chip. The RTC is optimised for ultra-low power consumption and incorporates built-in voltage level detection circuitry to monitor power supply status and voltage levels.
Features:
Provides year, month, day, day of the week, hour, minute and second based on a 32.768 kHz MEMS oscillator or quartz crystal
Supports daylight saving time mode and leap year compensation, with optional 24-hour or 12-hour formats
Automatic power-level detection and switching circuitry, which automatically switches to the backup battery power supply (VBAT) and continues to operate at extremely low current
Models supplied by Mingjiada Electronics:
SiT95901 – Ultra-low-power dual I²C clock real-time clock (RTC)
The SiT95901 is an ultra-low-power real-time clock (RTC) and calendar device with dual I²C bus support, allowing two master devices (i.e. the CPU and BMC chip in a server platform) to access the device.

In addition, Mingjiada Electronics supplies a wide range of electronic components, including integrated circuits (ICs), 5G chips, new energy ICs, IoT chips, Bluetooth chips and automotive chips, offering customers a one-stop procurement experience. Mingjiada Electronics maintains ample stock, with 2 million electronic component part numbers in stock, ensuring customers can quickly obtain the products they require. The company supports both small-batch sample purchases and large-volume orders to meet the needs of customers of all sizes.
