MK1574-01BSI

Clock Generators, PLLs, Frequency Synthesizers Overview

The MK1574-01BSI is a Phase-Locked Loop (PLL) based clock synthesizer designed for frame rate communications. It accepts an 8 kHz reference input and generates multiple locked output frequencies, including T1, E1, T2, and E2 rates. The device operates at 3.3 V and is housed in a 16-pin SOIC package. It supports industrial temperature ranges from -40°C to +85°C. Outputs are frequency-locked to the input, simplifying distribution in communication systems.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Accepts 8 kHz input clock and generates standard communication frequencies
• Three programmable outputs (CLK1, CLK2, CLK3) via FS pins
• Recovers and outputs 8 kHz clock with improved jitter characteristics
• Operates on 3.3 V supply voltage

Clock Generators, PLLs, Frequency Synthesizers Applications

• T1/E1/T2/E2 communication system clock generation
