The on-chip PLL includes a bypass mode, letting the design switch between a clean synthesised clock and a direct reference feed without an external mux. The PLL-with-bypass architecture means the device can generate a multiplied/cleaned clock from a lower-frequency crystal or pass through an external reference with the PLL disabled. This is useful during system test or when the board needs to synchronise to an external clock source without the PLL jitter. One input drives seven outputs. That 1:7 ratio eliminates a separate clock fanout buffer — the synthesizer and the distribution happen in one 20-pin TSSOP package, saving board area and reducing the BOM line count. All I/O are LVCMOS — no differential signalling. The outputs are single-ended, so the fan-out traces need impedance-matched routing if the clock edges are fast enough to cause reflections above a few centimetres. ## 20-TSSOP footprint and supply reality The package is 20-TSSOP, 4.40 mm wide.","metaTitle":"TI CDCEL937PWRG4 Clock Synthesizer, 230 MHz, 1.7-1.9V","metaDescription":"Texas Instruments CDCEL937PWRG4 clock/frequency synthesizer with PLL bypass, 230 MHz max output, 1:7 fanout, LVCMOS I/O, -40 to 85°C, 20-TSSOP.","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":"Clock/Frequency Synthesizer","Input":"LVCMOS, Crystal","Output":"LVCMOS","Series":"-","Package":"Tape & Reel (TR)","Mounting Type":"Surface Mount","Package / Case":"20-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":"CDCEL937","Ratio - Input:Output":"1:7","Operating Temperature":"-40°C~85°C","Supplier Device Package":"20-TSSOP","Differential - Input:Output":"No/No"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$118.8000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d0029fa64f7b5e05f8e80e54ac9e6a08.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the input-to-output ratio of CDCEL937PWRG4?","answer":"The ratio is 1:7 — a single input (LVCMOS or crystal) drives seven LVCMOS outputs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/CDCEL937PWRG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/CDCEL937PWRG4 when reusing this data.
