- AEC-Q100 automotive qualification ensures reliability across -40°C to +125°C temperature range for in-vehicle applications
- Enable/disable standby function reduces system power consumption when the clock is not needed in portable or automotive designs
- MEMS-based resonator eliminates fragile quartz crystal for improved shock and vibration resistance in harsh environments
Applications
The DSC6011CI2A-012.2880 is designed for automotive infotainment, audio codec clocking, and industrial communication interfaces requiring a precise 12.288 MHz reference in a compact 4-pin VDFN package. Its AEC-Q100 qualification makes it suitable for in-vehicle systems subject to vibration, extreme temperatures, and long service life requirements. The enable/disable pin allows system power management by gating the oscillator during low-power standby modes.

Frequently Asked Questions
Why is a 12.288 MHz frequency specifically useful for audio codec and telecom clocking applications?
12.288 MHz is an integer multiple of common audio sampling rates: it equals 256 times 48 kHz, a standard sample rate for professional audio and VoIP codecs. Most audio DSPs and telecom ICs derive their internal clocks from this frequency using simple integer dividers, making the DSC6011CI2A-012.2880 a direct drop-in clock source without fractional PLLs.
What AEC-Q100 grade does the DSC6011CI2A-012.2880 meet, and over what temperature range?
The DSC6011 series is qualified to AEC-Q100 Grade 1, covering the -40°C to +125°C automotive operating temperature range. This qualification includes stress tests for electrostatic discharge, latch-up, thermal cycling, and lifetime reliability, meeting automotive OEM requirements for dashboard electronics, ADAS modules, and in-cabin infotainment systems.
How does the MEMS resonator in the DSC6011CI2A-012.2880 compare to a quartz crystal oscillator for vibration-prone automotive installations?
MEMS resonators are inherently more robust than quartz crystals under mechanical shock and vibration. A quartz crystal can fracture or lose frequency calibration under 200 G shock, while MEMS resonators are fabricated as solid silicon structures and survive over 1000 G shock pulses. In automotive applications with road vibration and door-slam events, MEMS oscillators eliminate field failures caused by crystal fracture.
What output load does the DSC6011CI2A-012.2880 drive, and does it match typical CMOS input circuits?
The oscillator is specified for a 10 pF output load, which matches most CMOS logic inputs and microcontroller clock pins. CMOS inputs typically present 2 pF to 10 pF of capacitance, so the DSC6011 drives a single clock input directly without a buffer. The CMOS output logic levels (0 V to VDD) ensure compatibility with 1.8 V, 2.5 V, 3.3 V, and 5 V systems across its supply range.
