MK1574
Frame Rate Communications PLL
Description
The MK1574-01 is a Phase-Locked Loop (PLL)
based clock synthesizer, which accepts an 8 kHz
clock input as a reference, and generates many
popular communications frequencies. All outputs
are frequency locked together and to the input.
This allows for the generation of locked clocks to
the 8 kHz backplane clock, simplifying clock
generation and distribution in communications
systems.
MicroClock 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 kHz input clock
• Output clock rates include T1, E1, T2, E2
• 3.0V to 5.5V operation
• Available in commercial (0 to +70 C) or industrial
(-40 to +85 C) temperature ranges
• For jitter attenuation, use the MK2049
