Product details

Three jobs, one 64-pin package

It accepts HCSL, LVCMOS, LVDS, LVPECL, or crystal inputs and delivers CML, LVCMOS, LVDS, or LVPECL outputs across a 3:16 fanout from a single PLL core.

Output frequency ceiling — three rails

The maximum output frequency is specified at three tiers: 200 MHz, 1 GHz, and 3 GHz, depending on the output format and divider path selected. That 3 GHz top end puts this part in the range for 100G/400G line-card reference clocks or high-speed ADC/DAC sampling clocks where the jitter floor matters more than the raw frequency.

Package and mounting — 64-VFQFN with exposed pad

Housed in a 64-VFQFN exposed-pad package (9x9 mm body), surface-mount only.

Frequently asked questions

Is LMK5C33216RGCR pin-compatible with LMK5C33216RGCT?

The suffix RGCR vs RGCT indicates different tape-and-reel packaging options, not a pinout change. Both share the same 64-VFQFN package and are functionally identical — the RGCR is the standard reel quantity, RGCT is a smaller reel.

Does LMK5C33216RGCR require an external loop filter?

The device integrates the loop filter components internally for the PLL — no external RC network needed on the board. This saves board area and simplifies the layout versus older PLL clock generators.

Is LMK5C33216RGCR compatible with LVDS inputs?

Yes, LVDS is one of the accepted input formats alongside HCSL, LVCMOS, LVPECL, and crystal.
