The PLL includes a bypass mode, which lets the reference clock pass through unmodified when jitter performance or a clean system clock is the priority. Maximum output frequency reaches 230 MHz, covering common Ethernet, FPGA, and processor reference clock rates. ## Supply and temperature — narrow rail, industrial range ## Package and footprint — 24-TSSOP on 0.65 mm pitch The 4.40 mm body width keeps the footprint compact.","metaTitle":"CDCE949PWRG4 PLL Clock Generator, 230 MHz, 24-TSSOP","metaDescription":"Texas Instruments CDCE949PWRG4 PLL clock generator with bypass, 1:9 fanout, 230 MHz max, LVCMOS I/O, 1.7-1.9V supply, -40 to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"Mfr":"Texas Instruments","PLL":"Yes with Bypass","Type":"PLL Clock Generator","Input":"LVCMOS, Crystal","Output":"LVCMOS","Series":"-","Package":"Tape & Reel (TR)","Mounting Type":"Surface Mount","Package / Case":"24-TSSOP (0.173\\\", 4.40mm Width)","Frequency - Max":"230MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"1.7V ~ 1.9V","Divider/Multiplier":"Yes/No","Number of Circuits":"1","Base Product Number":"CDCE949","Ratio - Input:Output":"1:9","Operating Temperature":"-40°C~85°C","Supplier Device Package":"24-TSSOP","Differential - Input:Output":"No/No"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c2c2eaa0174ab99f12057213da9704ca.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CDCE949PWRG4/alternatives.json"},"ai":{"faq":[{"question":"Does CDCE949PWRG4 support LVCMOS output?","answer":"Yes, the CDCE949PWRG4 outputs LVCMOS levels on all nine outputs.
