Housed in a 4-VDFN with exposed pad (7.00 mm x 5.00 mm, 0.90 mm seated height), the package requires a thermal pad on the PCB to conduct heat to the ground plane — the exposed paddle is the primary thermal path, not the leads. Frequency stability is ±25 ppm across the full temperature range, which keeps the clock edge jitter within the timing budget for 10/100BASE-T Ethernet and most serial interfaces without external PLL tuning.","metaTitle":"DSC1522AI2A-12M80000 MEMS XO – 12.8 MHz, LVCMOS","metaDescription":"Microchip DSC1522AI2A-12M80000 MEMS oscillator: 12.8 MHz, LVCMOS output, ±25 ppm stability, -40°C to +85°C, 4-VDFN package.
