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

External Components/Crystal Selection
The MK1574 requires a minimum number of external components for proper operation. An RC network
(see Capacitor Selection on following page) should be connected between CAP1 and CAP2 as close to the
chip as possible. A high quality ceramic capacitor is recommended. A decoupling capacitor of 0.1µF must
be connected between VDD and GND pins (pins 2 and 3, 5 and 7) close to the chip, and 33terminating
resistors can be used on clock outputs with traces longer than 1 inch.

Notes:
1. Stresses beyond those listed under Absolute Maximum Ratings could cause permanent damage to the device. Prolonged exposure
to levels above the operating limits but below the Absolute Maximums may affect device reliability.
2. All multipliers as shown in the table on page two are exact, and are stored in ROM on the chip.
