200 MHz LVDS clock source for harsh environments
The DSC1123CL1-200.0000 is a 200 MHz LVDS MEMS oscillator from Microchip Technology, part of the DSC1123 series. The MEMS resonator inherently handles shock better than quartz — a real advantage on a vehicle's engine control unit or transmission module. The supply voltage range of 2.25V to 3.63V means it can run from a 2.5V or 3.3V rail without an extra regulator, simplifying the power tree. Maximum current draw is 32 mA, with a disable mode pulling 22 mA — useful for power-down sequencing during sleep states.
Housed in a 6-SMD no-lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm, the DSC1123CL1-200.0000 fits tight board stacks. The no-lead design requires a solder-paste stencil with good aperture-to-pad alignment — the 0.50mm pitch pads are small enough that a misaligned stencil can cause opens. Surface-mount assembly is standard; the package is compatible with reflow profiles typical for 6-pin ceramic oscillators.
Active production — sourcing to order
No official successor or second-source is listed — the DSC1123 family is the current offering. For volume requirements, confirm lead time and pricing at RFQ; the MEMS supply chain is generally stable, but allocation can shift during peak automotive cycles.
