MK2049-34SAILF

Overview

The MK2049-34SAILF is a VCXO-based PLL clock synthesizer operating at 3.3 V with an industrial temperature range of -40°C to +85°C. Packaged in a 20-pin SOIC, it accepts multiple inputs including 8 kHz backplane clocks or 10–36 MHz signals. It generates frequency-locked outputs such as T1, E1, T3, E3, ISDN, and OC3 submultiples with zero ppm error due to exact internal ratios. The device meets TR62411, ETS300 011, and GR-1244 specifications for Stratum 3, 4, and 4E timing performance.

Feature Summary

VCXO-based PLL architecture generating T1, E1, T3, E3, ISDN, xDSL, and OC3 submultiples from 8 kHz or MHz references
Buffer mode provides jitter attenuation for 10–36 MHz inputs with x1/x0.5 or x2/x4 output options
Zero delay feature ensures fixed phase relationship between input and output clocks
Compliant with TR62411, ETS300 011, and GR-1244 specifications for MTIE and jitter generation

Applications

Clock synchronization in communications systems requiring frequency-lock to 8 kHz backplane clocks
Jitter filtering for video clocks (e.g., 27 MHz) or high-jitter communication clocks
Loop timing applications for T1 and E1 input clocks

Procurement Notes

Verify the component status as the source indicates End-of-Life (EOL) for non-green parts occurred on 5/13/10. Confirm that the 'LF' suffix denotes Pb-free and RoHS compliance. Ensure the specific ordering suffix matches the required shipping packaging configuration.

Selection Notes

Select this part for applications requiring Stratum 3, 4, or 4E timing compliance. Ensure the design accommodates an external pullable crystal connected to pins X1 and X2. Verify that the input clock pulse width meets the minimum 10 ns requirement for 8 kHz inputs.

Part Context

This component belongs to the MK2049 family of 3.3 V communications clock VCXO PLLs. Related selections include the MK2049-34A, MK2049-36, and 5 V variants like the MK2049-01, -02, and -03. The MK2049-34SAILF specifically utilizes the lead-free SOIC package variant.
