MK2302S-01 Multiplier and Zero Delay Buffer Description Features The MK2302S-01is a high performance Zero Delay Buffer (ZDB) which integrates ICS’ proprietary analog/digital Phase Locked Loop (PLL) techniques. The chip is part of ICS’ ClockBlocksTM family and was designed as a performance upgrade to meet today’s higher speed and lower voltage requirements. The zero delay feature means that the rising edge of the input clock aligns with the rising edges of both output clocks, giving the appearance of no delay through the device. There are two outputs on the chip, one being a low-skew divide by two of the other output. • • • • • The MK2302S-01 is ideal for synchronizing outputs in a large variety of systems, from personal computers to data communications to graphics/video. By allowing off-chip feedback paths, the device can eliminate the delay through other devices. • • • • • • • 8 pin SOIC package Low input to output skew of 250ps max Absolute jitter ± 500ps Propagation Delay ± 350ps Ability to choose between different multipliers from 0.5X to 16X Output clock frequency up to 133 MHz at 3.3V Can recover degraded input clock duty cycle Output clock duty cycle of 45/55 Full CMOS clock swings with 25mA drive capability at TTL levels Advanced, low power CMOS process Operating voltage of 3.3V or 5V Industrial temperature version available Block Diagram IC L K S 1 :0 F B IN d ivid e by N P h a se D e te cto r, C h a rg e Pum p, and Loop F ilte r VCO C LK1 /2 C LK2 E x te rn a l fe e d b a ck c a n co m e fro m C L K 1 o r C L K 2 (se e ta b le o n p a g e 2 ) MDS 2302S-01 B 1 Revision 070803 Integrated Circuit Systems, Inc. ● 525 Race Street, San Jose, CA 95126 ● tel (408) 295-9800 ● www.icst.com MK2302S-01 Multiplier and Zero Delay Buffer Pin Assignment FBIN 1 8 CLK2 ICLK 2 7 VDD GND 3 6 CLK1 S0 4 5 S1 8 pin (150 mil) SOIC Clock Multiplier Decoding Table 1 (Multiplies Input clock by shown amount) FBIN S1 S0 CLK1 CLK2 CLK1 0 0 2 X ICLK ICLK CLK1 0 1 4 X ICLK 2 X ICLK CLK1 1 0 ICLK ICLK/2 CLK1 1 1 8 X ICLK 4 X ICLK CLK2 0 0 4 X ICLK 2 X ICLK CLK2 0 1 8 X ICLK 4 X ICLK CLK2 1 0 2 X ICLK ICLK CLK2 1 1 16 X ICLK 8 XICLK Pin Descriptions Pin Number Pin Name Pin Type 1 FBIN Input Feedback clock input. 2 ICLK Input Reference clock input. 3 GND Power Connect to ground. 4 S0 Input Select 0 for output clock per decoding table above.

It must be connected close to the part to minimize lead inductance. No external power supply filtering is required for this device. A 33W series terminating resistor can be used next to each output pin. Using CLK1 as the feedback will always result in synchronized rising edges between ICLK and CLK1. However, the CLK2 could be a falling edge compared with ICLK. ICS recommends using CLK2 feedback whenever possible. This will synchronize the rising edges of all three clocks. Absolute Maximum Ratings Stresses above the ratings listed below can cause permanent damage to the MK2302S-01. These ratings, which are standard values for ICS commercially rated parts, are stress ratings only. Functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over the recommended operating temperature range.
