3.5 GHz fanout buffer with 2:10 mux and military temp range
The CDCLVP111MVFREP is a 2:10 differential fanout buffer and multiplexer from Texas Instruments, accepting CML, LVDS, LVPECL, and SSTL inputs and delivering LVPECL outputs at up to 3.5 GHz. That 3.5 GHz ceiling means it can distribute a 10-Gigabit Ethernet reference clock or a high-speed ADC sampling clock without adding jitter from the distribution tree itself. The 2:10 ratio lets you select between two input sources and fan out to ten loads, which is useful for redundant clock architectures or splitting a master clock across multiple line cards. All ten outputs are differential LVPECL, so the signal integrity holds over short board traces to the receivers.
32-LQFP footprint and supply flexibility
Packaged in a 32-LQFP (7x7 mm) with 0.8 mm pitch — a common footprint that routes easily on a 4-layer board with a ground plane under the part.
No end-of-life notification or successor has been issued, so production programs can commit to this part without a near-term obsolescence risk.
How it compares to the CDCLVP1204RGTR
If your system needs more than four clock loads or must operate beyond 2 GHz or below -40°C, the CDCLVP111MVFREP is the necessary upgrade.
