The DSC1018BC1-054.0000 is a MEMS-based standard oscillator (XO) delivering a fixed 54 MHz CMOS output from a 1.8V supply rail.
Microchip lists the DSC1018BC1-054.0000 as Obsolete. No official successor is recorded from the original manufacturer.
Housed in a 4-SMD, No Lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm.
Yes, Microchip lists the DSC1018BC1-054.0000 as Obsolete. No official successor is documented. The part can be sourced through independent distribution on a lot-specific basis; confirm availability at RFQ.
Microchip does not list a direct pin-compatible replacement for this order code. A functional equivalent would require matching 54 MHz, CMOS output, 1.8V supply, ±50 ppm stability, and the 4-SMD no-lead package — but no single Microchip order code is documented as a drop-in successor. A board-level change may be necessary.
The oscillator operates from a 1.8V supply rail. The input voltage must be within the device's specified range; a 3.3V or 2.5V rail would require a regulator or level translator.
