135 MHz LVDS MEMS oscillator — BOM-fit note
The DSC1103CE2-135.0000T is a Microchip MEMS-based XO delivering a 135 MHz LVDS clock from a 2.25 V to 3.63 V supply rail. The LVDS output is differential — it pairs with a 100 Ω termination at the receiver and will not drive a single-ended CMOS input without a translator. The MEMS resonator gives it faster start-up and better shock tolerance than a quartz equivalent, which matters if the board sees vibration in a motor drive or outdoor telecom enclosure.
Standby function and disable current
A standby (power-down) pin on this oscillator drops the supply current to 95 µA max when asserted. For a battery-powered sensor node that sleeps most of the time, that disable current is low enough to leave the pin pulled low through a weak resistor without draining the cell. The active draw is 32 mA max at 135 MHz — budget that into the rail's peak load.
Housed in a 6-SMD no-lead package measuring 3.20 mm × 2.50 mm with a seated height of 0.90 mm. The -20°C to +70°C operating range covers commercial and most indoor industrial environments — not rated for engine-bay or outdoor pole-mount without an enclosure that keeps the ambient inside that band. The ±25 ppm frequency stability holds across that temperature span, so the clock edge jitter stays within the receiver's timing budget without external compensation.
