MK1574
Description
The MK1574-01 is a Phase-Locked Loop (PLL) based clock synthesizer, which accepts an 8 k Hz clock input as a reference, and generates many popular munications frequencies. All outputs are frequency locked together and to the input. This allows for the generation of locked clocks to the 8 k Hz backplane clock, simplifying clock generation and distribution in munications systems. Micro Clock can customize this device for any other different frequencies.
Features
- Packaged in 16 pin narrow (150 mil) SOIC
- Exact multiplications stored in the device eliminate the need for external dividers
- Accepts 8 k Hz input clock
- Output clock rates include T1, E1, T2, E2
- 3.0V to 5.5V operation
- Available in mercial (0 to +70 C) or industrial (-40 to +85 C) temperature ranges
- For jitter attenuation, use the MK2049
