Product details

MEMS oscillator at 14.7456 MHz — ±25 ppm stability

The 14.7456 MHz frequency is a standard baud-rate generator clock for UART and Ethernet controllers — it divides cleanly to common serial data rates without fractional-N PLL overhead.

The qualification includes reliability stress tests (HTOL, preconditioning, temperature cycling) per JEDEC JESD22 — the same tests that qualify an ECU microcontroller.

Product status is Active. The 6-SMD no-lead package (3.20 mm x 2.50 mm, 0.90 mm seated height) is a standard MEMS oscillator footprint.

Frequently asked questions

What is the frequency of DSC1121CI2-014.7456T?

The output frequency is 14.7456 MHz. This is a standard value for generating common serial baud rates — for example, 115200 baud requires a 14.7456 MHz clock with a simple divider.
