Obsolete — sourcing path for this MEMS XO
The DSC8103BI5-PROGRAMMABLE: This means the factory no longer manufactures the part; any available units are from remaining inventory or independent surplus channels. No pin-compatible direct replacement is listed; a board-level respin using a current-production MEMS oscillator from the same DSC8103 family may be the migration path.
What the key ratings mean for fit
As a MEMS-based XO (Standard) with LVDS output, this oscillator delivers a differential clock signal that rejects common-mode noise — suited for routing to a SerDes, FPGA, or high-speed ADC where single-ended clock jitter would degrade the signal-to-noise ratio. The LVDS swing stays within 350 mV typical, so the receiver must be LVDS-compatible or terminated to a 100 Ω differential pair. The available frequency range spans 10 MHz to 460 MHz, covering most base clocks for Ethernet PHYs, PCIe reference, and processor core timing.
Surface-mount reflow profile follows standard lead-free solder profiles; no moisture sensitivity level is stated, but bake before reflow if the part has been stored beyond the floor life of its MSL rating.
