Supply SiTime MHz Oscillators, Supply Digitally Controlled, Spread Spectrum And Voltage Controlled Oscillators

Shenzhen Mingjiada Electronics Co., Ltd. — offers a complete range of 【SiTime】 MEMS MHz oscillators, including: differential oscillators, LVCMOS oscillators, high-temperature oscillators, spread-spectrum oscillators, voltage-controlled oscillators and digital-controlled oscillators. Mingjiada Electronics stocks all mainstream models and supports both small-batch samples and large-volume orders. Backed by an efficient logistics system, we ensure rapid product delivery.

【SiTime】Digitally Controlled Oscillators
Details: SiTime’s digitally controlled MEMS oscillators (DCXOs) allow users to adjust the output frequency to within ±150,000 ppm via a single-wire digital interface. This eliminates the need for an external DAC required in traditional VCXO designs. Furthermore, it eliminates frequency drift caused by board noise on the voltage control line.
Features:
Wide pull range options, up to ±150,000 ppm
Tuning resolution of 1 ppb
Ultra-low power consumption and small footprint (SiT3901)
Wide frequency range (up to 625 MHz), supply voltages (1.8 V; 2.5 V to 3.3 V) and industry-standard packages (1508, 3225, 5032 or 7050)
LVCMOS output (SiT3907 and SiT3901) and differential output (SiT3921 and SiT3922)
Models supplied by Mingjiada Electronics:
SiT3907, SiT3921, SiT3922, SiT3521, SiT3522, SiT3901.

[SiTime] Spread-Spectrum Oscillators
Details: SiTime’s EMI-suppressed oscillators ensure compliance with radiation standards through spread-spectrum clocking and adjustment of clock signal rise/fall times. SiTime’s Time Machine II programmer supports these oscillators, enabling engineers to rapidly reduce radiation levels and ensure customer compliance with standards.
Features:
Fundamental frequency reduction of up to 17 dB; harmonic reduction of up to 30 dB
Wide spread: peak-to-peak spread of up to 4%
FlexEdge™ configurable rise/fall time options: 0.25 ns to 40 ns step size
Models supplied by Mingjiada Electronics: SiT9002, SiT9003, SiT9005.

[SiTime] Voltage-Controlled Oscillators
Details: SiTime MEMS VCXOs deliver exceptional dynamic performance and the highest reliability for video distribution (CMTS), networking, telecommunications and instrumentation applications. These devices are meticulously designed to maintain consistent phase noise and frequency tuning accuracy even under common environmental factors such as shock, vibration, power supply noise and electromagnetic interference (EMI). They enable equipment such as cable headends and remote radio heads (RRHs) to deliver the highest performance, optimum reliability and superior quality of service in uncontrolled environments, such as un-air-conditioned basements or rooftops.
Features:
Any frequency within the 1 MHz to 725 MHz range, in 1 Hz steps
±15 ppm, with optimal dynamic stability across the entire temperature range (-40 to +85°C)
0.02 ps/mV power supply noise rejection (PSNR), reducing power supply requirements
Optimal (0.1%) and widest (±25 to ±3200 ppm) pull range linearity, 50 times better than quartz
Models supplied by Mingjiada Electronics:
SiT3372, SiT3373, SiT3807, SiT3808, SiT3809.
