Unlike a quartz crystal, the MEMS resonator starts up faster and is more resistant to vibration and shock — a practical advantage in portable or industrial gear where a quartz can micro-crack on a drop. The 2.25V to 3.6V supply range means it can run directly off a 3.3V or 2.5V rail without an extra LDO — one less component to qualify. ## Frequency stability and power budget For a 24.576 MHz clock feeding a USB or Ethernet PHY, that keeps the bit-rate error well inside the spec — no need for a separate TCXO unless the system demands tighter than ±25 ppm. Maximum supply current is 22 mA. At 24.576 MHz with a CMOS load, that is the total draw including the output buffer — budget it into the rail's current allowance. Housed in a 6-SMD, No Lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm. The no-lead land pattern is a straightforward reflow-solder footprint — no through-hole, no hand-solder unless you have a hot-air station and a steady hand. The 0.90 mm height keeps it low-profile for mezzanine or card-edge clearance. Product status is Active.","metaTitle":"DSC1121BM1-024.5760 MEMS XO 24.576 MHz CMOS - Microchip","metaDescription":"DSC1121BM1-024.5760 XO (Standard) MEMS oscillator, 24.576 MHz, CMOS output, -55°C to 125°C, 2.25V-3.6V supply.

Package, supply voltage, temperature range, and pinout are identical. If your design can tolerate the 1.7% frequency difference (e.g., for a non-timing-critical clock), it is a drop-in swap. For a USB or Ethernet PHY that requires a precise 25.000 MHz, it will not work."},{"question":"How can I order DSC1121BM1-024.5760 or get a quote?","answer":"Submit an RFQ with your target quantity.
