Product status is Active — no EOL notice, no last-time-buy window.
The Enable/Disable pin pulls the output to high-Z and drops current to 22 mA max for power-gated designs.
Yes — the DSC1122 is pin-compatible with standard 7.0 mm x 5.0 mm 6-pad quartz XO footprints. The MEMS resonator gives faster start-up and better shock immunity than quartz, but the output is LVPECL, not LVCMOS — the receiver must accept differential levels. No external load caps needed.
