Product details

2.16 GHz clock conditioner with 1:8 fanout

The Texas Instruments LMK03033ISQE/NOPB is a clock conditioner that takes a single LVCMOS, LVDS, or LVPECL input and delivers eight conditioned, jitter-cleaned outputs in LVDS or LVPECL format, with a maximum frequency of 2.16 GHz.

This part is explicitly a clock conditioner, not a PLL-based synthesizer. It does not multiply or generate frequencies — it cleans up and distributes an existing reference clock across eight differential outputs. The divider is present (Yes on the divider/multiplier line), so you can divide down the input frequency, but there is no multiplication path. If your design needs frequency synthesis, this is not the part; if you need to buffer and distribute a clean 2.16 GHz clock with minimal additive jitter, it fits.

Supply rail and decoupling reality

The supply range is a tight 3.15V to 3.45V — 3.3V nominal with 150 mV of headroom either side. That means a clean, well-regulated 3.3V rail is mandatory; a switcher feeding this directly without post-regulation will push the supply out of spec under load transients. The pad is also the only ground return for the high-speed outputs, so the via count and placement directly affect signal integrity at 2.16 GHz.

Frequently asked questions

What is the maximum frequency this clock conditioner can handle?

The maximum frequency is 2.16 GHz on the input and outputs. Above that, the internal dividers and output drivers will not maintain the specified signal integrity.

What output formats does the LMK03033ISQE/NOPB support?

The eight outputs are configurable as LVDS or LVPECL differential pairs. The input side accepts LVCMOS, LVDS, or LVPECL, so it can interface with most common high-speed logic families.

Does this part have a PLL for frequency synthesis?

No, the PLL field is listed as No. This is a clock conditioner and fanout buffer, not a frequency synthesizer. It cleans and distributes an existing reference clock; it does not multiply the frequency.
