The MK1574-01A/B are Phase-Locked Loop (PLL) based clock synthesizers, which accept an 8 kHz clock input as a reference, and generate 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. 1) MK1574-01A — 5 V operation 2) MK1574-01B — 3.3 V operation IDT manufactures the largest variety of clock generators and buffers, and can customize this device for a variety of frequencies.
