Active production — 2.6 GHz PLL clock generator with 14 outputs
The LMK03806BISQE/NOPB is a Texas Instruments clock generator IC with an integrated PLL that includes a bypass mode, capable of synthesizing clocks up to 2.6 GHz from a single input source (LVCMOS, LVDS, LVPECL, or crystal). It fans out to 14 differential outputs, each programmable for LVCMOS, LVDS, or LVPECL levels, making it a central clock-tree device for high-speed ADC/DAC, FPGA, or SerDes reference clocks. The 1:14 ratio means one reference input drives fourteen independent clock outputs — a single chip replaces a multi-stage distribution buffer tree, saving board space and reducing jitter accumulation across fan-out stages.
The device operates from a 3.15V to 3.45V supply, which aligns with standard 3.3V logic rails.
Sourcing and compliance — active production, ROHS3, cut tape available
The suffix /NOPB confirms ROHS3 compliance and lead-free construction. For BOM planning: the base product number LMK03806 covers the whole family; the BISQE/NOPB suffix specifies the 64-WQFN package and ROHS3 finish. The sibling variant LMK03806BISQ (without /NOPB) is the same die in the same package but may carry a different lead-finish compliance — confirm the BOM's RoHS requirement before substituting.
