1.5 GHz clock synthesis with multi-protocol I/O
The CDCE62005RGZR is a clock generator from Texas Instruments integrating a PLL with bypass mode, capable of synthesizing output clocks up to 1.5 GHz from a single reference input. It accepts LVCMOS, LVDS, LVPECL, or crystal inputs and can deliver the same output formats, making it suitable for clock trees that must bridge different logic families on the same board. The 3:5 input-to-output ratio allows up to five independent clock domains from one reference, reducing the number of oscillators in a design.
Housed in a 48-VFQFN with exposed pad (7x7 mm), the package requires a thermal land on the PCB for heat sinking — the exposed pad must be soldered to the ground plane to achieve the rated thermal performance. Surface-mount assembly; the 0.5 mm pitch QFN demands careful stencil design and reflow profile control to avoid solder bridging.
