That frequency and output type are a standard reference for PCIe Gen 3/4, 10 GbE, and other high-speed serial interfaces where the HCSL swing and common-mode range match the receiver's input stage without external level translation. The ±20 ppm frequency stability holds the clock edge jitter within the timing budget for a 156.25 MHz reference — a 50 ppm crystal would eat into the UI margin on a 10 Gbps link. ## Standby power-down saves battery in duty-cycled systems The 40 mA typ active draw is typical for a 156.25 MHz HCSL driver. ## Industrial temp grade and 6-VDFN package The 6-VDFN package (2.50 mm x 2.00 mm, 0.90 mm seated height) is a standard footprint for MEMS oscillators — check the land pattern against your layout before committing.","metaTitle":"DSC1204DI3-156M2500T 156.25 MHz HCSL MEMS Oscillator","metaDescription":"Active XO (Standard) with HCSL output, 156.25 MHz, ±20 ppm stability, -40 to 85°C, standby power-down.
