PLL with bypass — clock-tree design flexibility
The CDCEL824PWR integrates a PLL with bypass capability, meaning the internal phase-locked loop can be engaged for frequency synthesis or bypassed entirely to pass the reference clock through cleanly — useful when you need a jitter-cleaned clock at one output and a raw reference at another. The PLL accepts either an LVCMOS reference or a crystal oscillator input, giving the board designer a choice between a cheap discrete crystal and a buffered CMOS clock source depending on the phase-noise budget and board area constraints. Because the input-to-output path is non-differential (single-ended LVCMOS in and out), the part is suited for single-ended clock distribution in cost-sensitive designs rather than differential pairs like LVPECL or LVDS that require termination resistors and tighter layout.
201 MHz ceiling and 1:4 fanout — how many loads it drives
The maximum output frequency of 201 MHz covers common clock domains for Ethernet PHYs, FPGAs, and DDR memory controllers — but the 1:4 ratio means each of the four outputs can run at a different frequency derived from the same PLL, as long as none exceeds 201 MHz. With a 1:4 input-to-output ratio, a single reference clock feeds up to four independent clock domains; the divider/multiplier block lets each output be scaled independently without adding external fanout buffers.
Active lifecycle — no design-in risk
The part ships in 16-TSSOP (4.40 mm width) on tape and reel, compatible with standard pick-and-place assembly; the 0.65 mm pin pitch is layout-friendly on two-layer boards.
