Description

The MK74ZD133 is a monolithic CMOS high speed clock driver that includes an on-chip PLL (Phase Locked Loop). Ideal for communications and other systems that require a large number of high-speed clocks, the unique combination of PLL and 32 outputs can eliminate oscillators and multiple low skew buffers. With 32 outputs included in one device, there is also no need to worry about chip-to-chip skew. The zero delay modes cause the input clock rising edge to be synchronized with all of the outputs’ rising edges.

Features

? 56 pin SSOP or 64 pin LQFP package

? On-chip PLL generates output clocks up to 80 MHz (SSOP) or 133.33 MHz (LQFP)

? Zero delay plus multiplier function

? 32 low-skew outputs can eliminate chip-to-chip skew concerns in systems with less than 33 clocks

? Output to output skew of 200 ps (with stagger)

? Device to device skew of 700ps

? Staggered, fixed skew helps reduce EMI

? Tri-state (Output Enable) pin

? Output blocks can be independently powered off

? 250 ps typical fixed delay between input and output in “Multiplier” mode

? Ideal for Fast Ethernet and Gigabit Ethernet designs

? Good for video servers

? 3.3V±5 supply voltage
