Product details

Output type and termination — LVPECL signal integrity

LVPECL output delivers a differential signal with typical 800 mV swing across a 50 Ω load to VCC - 2 V. The 100 MHz frequency is a common reference for Ethernet PHYs, FPGAs, and SerDes transceivers.

Supply and power budget — 3.3 V rail, 208 mA max

Operates from a single 3.3 V supply. Maximum supply current is 208 mA when enabled; disabling the output via the Enable/Disable pin drops the current to 136 mA max. That 72 mA saving matters in battery-backed or thermally constrained designs where the oscillator cannot be fully power-gated.

Housed in a 6-SMD Module measuring 7.00 mm x 5.00 mm with a seated height of 1.15 mm. Surface-mount, compatible with standard reflow profiles.

Frequently asked questions

What is the exact frequency of LMK61E2-100M00SIAT?

The LMK61E2-100M00SIAT is a fixed 100 MHz oscillator. No programmable or configurable frequency option — it ships at 100 MHz.

Does LMK61E2-100M00SIAT have an enable/disable function?

Yes, it includes an Enable/Disable pin. When disabled, the supply current drops from 208 mA max to 136 mA max, allowing power savings in idle or standby modes.

What is the output type of LMK61E2-100M00SIAT?

LVPECL (Low-Voltage Positive Emitter-Coupled Logic) differential output. It requires a DC bias network — typically 50 Ω to VCC - 2 V — for proper termination.
