No PLL inside, so there is no frequency multiplication or phase locking; the output is a modulated version of the input, not a multiplied clock. Max output is 108 MHz, which covers most microcontroller, FPGA, and serial-interface reference clocks. Supply voltage is 3V to 3.6V — a tight 3.3V ±0.3V window. If your board already has a 3.3V rail, this part drops in. If you are running 5V or 1.8V logic, you need an additional regulator. The output is LVCMOS, so it drives standard CMOS inputs directly without level translation. ## Industrial temperature and package fit Suitable for outdoor telecom, motor drives, and factory automation where the ambient can swing. The 8-TSSOP package has a 4.40 mm body width and 0.65 mm pin pitch — a standard footprint that routes easily on two-layer boards. Surface-mount only. The 1:1 input-to-output ratio means one crystal drives one clock output. If you need to fan out to multiple loads, add a clock buffer after this device. ## Sourcing and lifecycle posture Production continues. ROHS3 compliant, so it meets the latest EU lead-free directive. No known successor or cross-reference from TI; this is the current-generation part. Sourced to order against your BOM quantity — confirm lead time and pricing at quote. No stock-holding claim; we source per RFQ from our supply network.","metaTitle":"CDCS502PW Texas Instruments Spread Spectrum Clock Driver","metaDescription":"CDCS502PW active Spread Spectrum Clock Driver from TI.
