It accepts LVCMOS, LVDS, or LVPECL inputs and provides eight differential LVDS or LVPECL outputs from two input references, with a maximum output frequency of 800 MHz. ## 800 MHz ceiling and the 3.3V supply rail The 800 MHz maximum frequency sets the upper bound for the clock-tree tier this part can serve — it handles 10GbE reference clocks, FPGA transceiver refclks, and ADC/DAC sampling clocks in that band. The supply range is 3.15 V to 3.45 V, a tight 3.3 V ±0.15 V window; the board's 3.3 V rail must stay within that envelope under load, or the PLL may lose lock or the output jitter degrades.","metaTitle":"LMK02000ISQX/NOPB Clock Conditioner, 800 MHz","metaDescription":"Texas Instruments LMK02000ISQX/NOPB clock conditioner with PLL, 800 MHz max, LVDS/LVPECL outputs, -40°C to 85°C.","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 Conditioner","Input":"LVCMOS, LVDS, LVPECL","Output":"LVDS, LVPECL","Series":"-","Package":"Tape & Reel (TR)","Mounting Type":"Surface Mount","Package / Case":"48-WFQFN Exposed Pad","Product Status":"Obsolete","Frequency - Max":"800MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3.15V ~ 3.45V","Divider/Multiplier":"Yes/No","Number of Circuits":"1","Base Product Number":"LMK02000","Ratio - Input:Output":"2:8","Operating Temperature":"-40°C~85°C","Supplier Device Package":"48-WQFN (7x7)","Differential - Input:Output":"Yes/Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$19.1000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/67a3ed2144e606a8399588d0b4c1ae48.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the best replacement for LMK02000ISQX/NOPB?","answer":"No official successor or direct replacement is listed on the record for the LMK02000ISQX/NOPB.
