The 1:6 fanout ratio means this single 20-SSOP device replaces a separate PLL plus a clock buffer, saving board area and reducing jitter accumulation from cascaded stages. The maximum output frequency of 36.87 MHz sets the upper bound for the clock tree. If your system has a 50 MHz Ethernet MAC or a 48 kHz audio master clock derived from a PLL, this part covers the audio and lower-speed serial interfaces but not the gigabit Ethernet or high-speed ADC clock domains. The 36.87 MHz ceiling is typical for multi-clock generators targeting audio codecs, set-top boxes, and industrial control where the fastest peripheral clock is the SPI bus or the audio bit clock. This dual-voltage flexibility is useful when the PLL sits on a mixed-voltage board: the core logic runs at 3.3 V while legacy peripheral interfaces still use 5 V. ## Temperature grade: indoor industrial, not under-hood If your design must survive a cold start at -40°C, look at the industrial-temperature variants in the PLL1700 family. For a new design, this means you can commit the BOM line without worrying about a sudden obsolescence-driven redesign.","metaTitle":"PLL1700EG4 PLL Multi-Clock Generator, 36.87 MHz, 20-SSOP","metaDescription":"Active PLL1700EG4 from Texas Instruments: PLL multi-clock generator, 36.87 MHz max, 3.3V/5V supply, 1:6 fanout, -25°C to 85°C, 20-SSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"Mfr":"Texas Instruments","PLL":"Yes","Type":"PLL Multi-Clock Generator","Input":"TTL","Output":"CMOS","Series":"-","Package":"Tube","Mounting Type":"Surface Mount","Package / Case":"20-SSOP (0.209\\\", 5.30mm Width)","Frequency - Max":"36.87MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3.3V, 5V","Divider/Multiplier":"No/No","Number of Circuits":"1","Base Product Number":"PLL1700","Ratio - Input:Output":"1:6","Operating Temperature":"-25°C~85°C","Supplier Device Package":"20-SSOP","Differential - Input:Output":"Yes/No"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum output frequency of PLL1700EG4?","answer":"The maximum output frequency is 36.87 MHz.
