HCSL (High-Speed Current Steering Logic) swings 700-900 mV peak-to-peak into a 50-Ω terminated differential pair; the 156.25 MHz edge rate is fast enough that the PCB trace length mismatch between the P and N legs should stay under 5 mils to keep the crossing point centered. Supply range spans 2.25V to 3.6V — it runs from a 2.5V or 3.3V rail directly, no extra LDO needed; the 42 mA max draw at 3.3V (139 mW) is manageable in the 2.5 mm × 2.0 mm 6-SMD package as long as the board has a copper pour under the part.","metaTitle":"DSC1104DI1-156.2500 – Microchip 156.25 MHz HCSL MEMS","metaDescription":"DSC1104DI1-156.2500: Microchip MEMS XO, 156.25 MHz HCSL output, ±50 ppm stability, 2.25-3.6V, -40°C to +85°C.
