It serves as a precision clock reference in space-constrained, battery-powered systems including IoT edge nodes and automotive surround-view cameras.

For engineers reviewing the DSC6101CI2A-020.0000 datasheet, DSC6101CI2A-020.0000 pinout, DSC6101CI2A-020.0000 application, or DSC6101CI2A-020.0000 equivalent, key selection criteria include its 1.6 mm × 1.2 mm VFLGA package, OE/STBY/FS pin functionality, 9.5 psRMS period jitter at 27 MHz (scalable to 20 MHz), industrial temperature rating, and drop-in compatibility with 4-pin CMOS quartz oscillators.

Technical Context

The DSC6101CI2A-020.0000 integrates a MEMS resonator with on-chip temperature sensor, control & compensation logic, PLL-based VCO, and programmable output divider to deliver stable 20 MHz output across voltage (1.71–3.63 V) and temperature (–40°C to +85°C). Its digital control architecture enables frequency select (FS) mode and output enable (OE) or standby (STBY) operation via Pin 1.

This variant uses standard-drive (DSC61x1) output buffer delivering >3 mA drive capability into 10 pF load, with 1.2–2.2 ns rise/fall time depending on VDD. Startup time is ≤1.3 ms from 90% VDD, and it supports monotonic power ramp profiles up to 100 ms.

FAQ

What is the operating voltage range for the DSC6101CI2A-020.0000?

The DSC6101CI2A-020.0000 operates from 1.71 V to 3.63 V, supporting common logic rails including 1.8 V, 2.5 V, and 3.3 V systems. Its supply regulation circuitry maintains stable 20.0000 MHz output across this full range, with active current specified at 3.0 mA typical at 1.8 V and 27 MHz (scaling linearly with frequency and voltage).

Does the DSC6101CI2A-020.0000 require external load capacitors?

No, the DSC6101CI2A-020.0000 is a fully integrated MEMS oscillator and does not require external load capacitors. It only requires a 0.1 µF ceramic bypass capacitor placed adjacent to Pin 4 (VDD) to suppress supply noise - no crystal load caps, series resistors, or termination networks are needed.

How is the DSC6101CI2A-020.0000 pin 1 configured, and what function does it serve?

Per the product identification system, the 'C' in DSC6101CI2A-020.0000 indicates Pin 1 is configured as Output Enable (OE) with internal 300 kΩ pull-up. When driven high, the DSC6101CI2A-020.0000 outputs 20.0000 MHz; when pulled low, the output enters high-impedance state - enabling dynamic clock gating in power-sensitive designs.

Is the DSC6101CI2A-020.0000 qualified for automotive applications?

Yes, the DSC6101CI2A-020.0000 is AEC-Q100 qualified for automotive use. Its 'I' suffix denotes industrial temperature range (–40°C to +85°C), and the DSC61xx family meets AEC-Q100 stress test requirements for thermal cycling, mechanical shock, and vibration - making it suitable for rear-view and surround-view camera modules.

What is the startup time specification for the DSC6101CI2A-020.0000?

The DSC6101CI2A-020.0000 has a maximum startup time of 1.3 ms, defined as the interval from when VDD reaches 90% of its final value to when the output clock achieves valid logic levels and stable frequency. This applies across the full operating temperature and voltage range, ensuring predictable boot timing in real-time systems.
