Suggested models are M1600s and M1700s which use 10KH ECL logic, or low jitter models shown on M2910 data sheet which are available thru 410MHz. Description MF Electronics' high speed clock oscillators for digital and communications applications are based on 5V ECL logic and are available in full size (M) and half size (H) thru-hole packages. Designed in ECL 10K logic, the oscillators deliver 10 MHz to 125 MHz output. All models are available in complementary output, and a choice of either negative (ECL) or positive (PECL) operating voltage. These models are intended for designs which interface with 10K logic. For superior performance, see our models using 10KH or ECLPS.
