Supply voltage spans 2.5 V to 3.3 V, so it runs from a common 3.3 V or 2.5 V rail without an external regulator; the LVPECL output is AC-coupled into the PHY or FPGA clock input. The part ships in Tape & Reel (TR) packaging, the standard format for automated pick-and-place assembly; the 6-VDFN package measures 7.00 mm x 5.00 mm with a seated height of 0.90 mm. During normal operation the supply current is 50 mA typ, which is typical for a 156.25 MHz LVPECL output driving a 50-ohm terminated line. ## Temperature range and stability for indoor gear The stability figure covers the full temperature range, supply variation, and ageing.","metaTitle":"DSC1202NE2-156M2500T Microchip XO LVPECL 156.25 MHz MEMS","metaDescription":"Active Microchip MEMS XO, LVPECL output at 156.25 MHz, ±25 ppm stability, 2.5-3.3 V supply, 6-VDFN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"LVPECL","Series":"DSC1202","Package":"Tape & Reel (TR)","Ratings":"-","Function":"Standby (Power Down)","Frequency":"156.25 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-VDFN","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.276\\\" L x 0.197\\\" W (7.00mm x 5.00mm)","Voltage - Supply":"2.5V ~ 3.3V","Frequency Stability":"±25ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-20°C~70°C","Current - Supply (Max)":"50mA (Typ)","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"5µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the exact output type of DSC1202NE2-156M2500T?","answer":"LVPECL — Low-Voltage Positive Emitter-Coupled Logic.
