27 MHz MEMS oscillator for automotive and industrial timing
The DSC1001DL1-027.0000T is a 27 MHz MEMS-based XO from Microchip's DSC1001 series, delivering a CMOS output from a 1.8V to 3.3V supply rail. The MEMS resonator inherently withstands higher g-levels than a quartz crystal — a practical advantage on a PCB near a solenoid valve or cooling fan.
Standby function and power budget
A standby (power-down) pin drops the supply current to 15 µA max, letting the system clock be gated without a separate load-switch. Active current is 7.2 mA max at 27 MHz — low enough that a 3.3V rail feeding both the oscillator and a small MCU stays within a 100 mA LDO budget.
Package and board-fit note
The 4-SMD no-lead package measures 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a compact footprint that fits tight card-edge layouts in automotive camera modules or sensor nodes. Frequency stability is ±50 ppm across the operating range, so the clock edge jitter stays within the timing budget of a 27 MHz CAN-FD or Ethernet PHY reference.
