14.3182 MHz MEMS oscillator for video and legacy timing
The DSC1033CI1-014.3182T is a MEMS-based XO (Standard) from Microchip's PureSilicon™ series, delivering a 14.3182 MHz CMOS output at 3.3 V supply. That frequency is the NTSC colour-burst subcarrier divided by four — a common reference for video encoders, legacy graphics controllers, and set-top boxes still running 480i/576i timing.
For a battery-powered sensor logger that sleeps 99% of the time, the oscillator's own draw becomes negligible — the 1 µA leakage is below most LDO quiescent currents. The standby pin is active-low; pulling it high or leaving it floating keeps the output running.
Housed in a 4-SMD no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. The 0.50 mm pitch land pattern matches the standard 3225 footprint used by quartz oscillators — a direct layout swap if you are migrating from a quartz XO to MEMS. No exposed paddle, so reflow profile is straightforward; the part survives standard lead-free soldering without a moisture bake if handled per MSL 1.
Listed as Active by Microchip. No EOL notice or successor announced — the DSC1033 series remains a current production line.
