This part generates differential LVDS or LVPECL outputs from a single-ended input — the PLL multiplies the reference frequency up to the 1.2 GHz ceiling, covering the clocking needs of high-speed serial links, data converters, and FPGA transceivers. ## Supply, package, and temperature grade Housed in a 24-VQFN with exposed pad (4x4 mm body), the package requires a thermal land on the PCB to pull heat from the die. Texas Instruments has marked the CDCE421RGETG4 as obsolete.","metaTitle":"Texas Instruments CDCE421RGETG4 Clock Generator, 1.2 GHz","metaDescription":"Texas Instruments CDCE421RGETG4 clock generator with PLL, 1.2 GHz max frequency, LVDS/LVPECL outputs, 24-VQFN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Clock & Timing ICs"],"specifications":{"Mfr":"Texas Instruments","PLL":"Yes","Type":"Clock Generator","Input":"LVCMOS, Crystal","Output":"LVDS, LVPECL","Series":"-","Package":"Tape & Reel (TR)","Mounting Type":"Surface Mount","Package / Case":"24-VFQFN Exposed Pad","Product Status":"Obsolete","Frequency - Max":"1.2GHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 3.6V","Divider/Multiplier":"Yes/No","Number of Circuits":"1","Base Product Number":"CDCE421","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C~85°C","Supplier Device Package":"24-VQFN (4x4)","Differential - Input:Output":"No/Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2ee59c1530c76bd33b309641bc7cb932.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CDCE421RGETG4/alternatives.json"},"ai":{"faq":[{"question":"What output standards does the CDCE421RGETG4 support?","answer":"The device outputs differential LVDS or LVPECL signals.
