| ICS2402 Multiplier and Zero Delay Buffer Description The ICS2402 is 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. The ICS2402 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.

It must be connected close to the part to minimize lead inductance. No external power supply filtering is required for this device. A 33 series terminating resistor can be used next to each output pin. Absolute Maximum Ratings Stresses above the ratings listed below can cause permanent damage to the ICS2402. 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.
