LMK60A0-148351: Device technology

Hi Tom, 

Just to confirm, when you mention LMK6x are you referring to our LMK6C/P/D/H BAW oscillators? Or is it the LMK60 family as indicated in the title of the thread? 

In either case, we don't produce standalone crystals or other types of passive resonators. All of our oscillator devices also include active circuitry as well. 

Regards,

In a previous version of this post, I was completely wrong about the LMK60 and LMK61 devices, so I deleted it and re-posted to avoid confusing anyone else who reads this thread in the future. Apologies for the confusion.

LMK60 and LMK61 families use an integrated crystal and crystal driver for a reference, and a fractional PLL to synthesize arbitrary frequencies from that reference. The crystal driver and the fractional PLL are both active circuits on the same die, and the die is silicon based and produced by TI. The crystal is externally sourced. The fractional PLL consumes 150-200mA at 3.3V - generally the power consumption is high enough that we don't recommend it as a crystal oscillator replacement unless there is a particular frequency requirement that cannot be satisfied by an existing XO.

LMK6C/P/D/H family uses a free-running solid-state BAW oscillator for the internal reference, and a fractional output divider to synthesize arbitrary frequencies from that reference. The BAW oscillator and the fractional output divider are separate dies, bonded internally; they are both produced by TI and are both silicon-based. The fractional output divider consumes around 50-s0mA at 1.8V to 3.3V. We have some literature on the differences between LMK6C/D/P/H devices vs crystal oscillators which goes into much greater detail, see https://www.ti.com/lit/an/snaa362/snaa362.pdf.
