19.2 MHz LVDS clock with MEMS reliability
The DSC1103DI2-019.2000 is a 19.2 MHz LVDS oscillator from Microchip's DSC1103 series, built on a MEMS resonator instead of a quartz crystal. LVDS output gives clean differential signalling for high-speed clocks — the 32 mA supply max reflects the current needed to drive the 100-ohm termination pair. That means the clock edge jitter stays tight enough for a 100BASE-TX PHY or a mid-range FPGA PLL without external tuning components. Supply voltage spans 2.25 V to 3.63 V, covering 2.5 V and 3.3 V rails with margin.
Standby mode for power-sensitive builds
The MEMS resonator starts up faster than a quartz crystal — no millisecond wait for oscillation to stabilise. That matters for duty-cycled systems where every microsecond of wake time burns battery.
6-SMD footprint and board integration
Housed in a 6-SMD no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm. The small footprint fits tight channel spacing on a 10 GbE switch or a compact radio module — no room wasted around the clock source. The 0.90 mm height keeps it under low-profile shielding cans.
The DSC1103 series remains a current design-in part from Microchip — no last-time-buy pressure for new builds. Sourced through independent distribution against your BOM quantity.
