16 OUTPUT LOW SKEW CLOCK GENERATOR DATASHEET MK74CG117B The MK74CG117B is a monolithic CMOS high speed, low-skew clock driver that includes an on-chip PLL. Ideal for communications and other systems that require a large number of high-speed clocks, the unique combination of PLL and 16 low-skew outputs can eliminate oscillators and low skew buffers from systems. The device has a number of built in multipliers, making it possible to run from one inexpensive, low frequency crystal, and produce high frequency clock outputs. Another selection allows the chip to run as a divider, dividing the input clock by two or 4 using the mode select . The device also has a buffered reference output, allowing multiple devices to be easily driven from one clock source. • 48-pin SSOP 300 mil package • On-chip PLL generates output clocks up to 100 MHz from a simple crystal or clock input • 16 low-skew outputs • Output skew less than 250 ps on rising edges • Ability to configure as: 16 clocks at full frequency 12 at full and 4 at half frequency 8 at full and 8 at half frequency • Tri-state mode for Output Enable function • V ±5% supply voltage • Industrial temperature version available NOTE EOL for non-green parts to occur on 5/13/10 per PDN U-09-01 Block Diagram S2:0 2 M1:0 Crystal or X1/ICLK clock input Crystal Ocsillator The crystal requires external capacitors for accurate tuning of the clock VDD 9 Clock Synthesis and Mode Select Circuitry 10 GND IDT 16 OUTPUT LOW SKEW CLOCK GENERATOR Clock 1 Clock 2 Clock 16 REF MK74CG117B 16 OUTPUT LOW SKEW CLOCK GENERATOR Pin Assignment VDD 1 X1/ICLK 2 X2 3 NC 4 NC 5 GND 6 GND 7 S2 8 REF 9 S1 10 GND 11 GND 12 CLK1 13 CLK2 14 VDD 15 VDD 16 CLK3 17 CLK4 18 GND 19 GND 20 NC 21 CLK5 22 CLK6 23 VDD 24 48 S0 47 CLK16 46 VDD 45 VDD 44 NC 43 CLK15 42 CLK14 41 GND 40 GND 39 M1 38 CLK13 37 CLK12 36 VDD 35 VDD 34 M0 33 CLK11 32 CLK10 31 CLK9 30 VDD 29 NC 28 GND 27 GND 26 CLK8 25 CLK7 48-pin 300 mil SSOP CLOCK SYNTHESIZER IDT 16 OUTPUT LOW SKEW CLOCK GENERATOR MK74CG117B 16 OUTPUT LOW SKEW CLOCK GENERATOR CLOCK SYNTHESIZER Pin Descriptions Pin Number Pin Name Pin Type Pin Description Ordering Information SEATING PLANE aaa C Part / Order Number MK74CG117BF* MK74CG117BFT* MK74CG117BFLF MK74CG117BFLFT MK74CG117BFI* MK74CG117BFIT* MK74CG117BFILF MK74CG117BFILFT Marking MK74CG117BF 74CG117BFLF MK74CG117BFI 74CG117BFILF Shipping Packaging Tubes Tape and Reel Tubes Tape and Reel Tubes Tape and Reel Tubes Tape and Reel Package 48-pin SSOP 48-pin SSOP 48-pin SSOP 48-pin SSOP 48-pin SSOP 48-pin SSOP 48-pin SSOP 48-pin SSOP Temperature 0 to +70° C 0 to +70° C 0 to +70° C 0 to +70° C -40 to +85° C -40 to +85° C -40 to +85° C -40 to +85° C *NOTE EOL for non-green parts to occur on 5/13/10 per PDN U-09-01 While the information presented herein has been checked for both accuracy and reliability, Integrated Device Technology, Inc.

DATASHEET

MK74CG117B

The MK74CG117B is a monolithic CMOS high speed, low-skew clock driver that includes an on-chip PLL. Ideal for communications and other systems that require a large number of high-speed clocks, the unique combination of PLL and 16 low-skew outputs can eliminate oscillators and low skew buffers from systems.

The device has a number of built in multipliers, making it possible to run from one inexpensive, low frequency crystal, and produce high frequency clock outputs. Another selection allows the chip to run as a divider, dividing the input clock by two or 4 using the mode select .

The device also has a buffered reference output, allowing multiple devices to be easily driven from one clock source.
• 48-pin SSOP 300 mil package
• On-chip PLL generates output clocks up to 100 MHz from
a simple crystal or clock input
