156.25 MHz LVDS clock source with MEMS reliability
The DSC1123CE1-156.2500 is a 156.25 MHz LVDS oscillator from Microchip's DSC1123 series, built on a MEMS resonator rather than a quartz crystal. That MEMS base gives it better resistance to shock and vibration compared to a traditional crystal oscillator — useful if the board lives in a vehicle or on a factory floor where mechanical stress is a given. The LVDS output delivers a differential signal with low jitter, which is what you want when clocking a high-speed ADC, a SerDes, or an FPGA that needs a clean 156.25 MHz reference for Ethernet or video timing.
Supply range and enable/disable control
The enable/disable function lets you gate the output — pull the enable pin low and the oscillator stops, drawing 22 mA max in the disabled state versus 32 mA max when active.
Automotive qualification and temperature grade
Rated AEC-Q100, this oscillator is qualified for automotive applications.
Package and board layout
Housed in a 6-SMD, no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. The small footprint and low profile make it a fit for space-constrained PCBs — just keep the LVDS trace pair impedance-controlled and route them with matched length to preserve signal integrity at 156.25 MHz.
