Product details

1.2 GHz PLL clock generator — obsolete, last-time-buy managed

The CDCE421RGET is a Texas Instruments clock generator with an integrated PLL, accepting LVCMOS or crystal inputs and delivering differential LVDS or LVPECL outputs up to 1.2 GHz.

24-VQFN footprint and board integration

Housed in a 24-VFQFN exposed-pad package (4x4 mm body, 24-VQFN supplier package), the CDCE421RGET requires a thermal pad on the PCB for heat dissipation.

Texas Instruments has marked the CDCE421RGET as Obsolete. Sourcing is through independent distribution — confirmed against an RFQ, with availability and pricing quoted at time of request.

Frequently asked questions

What is the maximum output frequency of the CDCE421RGET?

The CDCE421RGET generates differential LVDS or LVPECL clock outputs up to 1.2 GHz. The PLL locks to the LVCMOS or crystal input and multiplies it to this ceiling.

What package does the CDCE421RGET use?

It comes in a 24-VFQFN exposed-pad package (4x4 mm, 24-VQFN supplier device package).
