No Preview Available ! November 2006 rev 0.3 ASM2P2310A 2.5-V TO 3.3-V High-Performance Clock Buffer Features • High-Performance 1:10 Clock Driver for General Purpose applications. Operates up to 200 MHz at 3.3V Supply Voltage • Pin-to-Pin Skew < 100 pS at 3.3V Supply Voltage • Supply Range : 2.3V to 3.6V • Operating Temperature Range : -40°C to 85°C • Output Enable Glitch Suppression • Distributes One Clock Input to Two Banks of Five Outputs • 25Ω On Chip Series Damping Resistors • Packaged in 24 Pin TSSOP Package Block Diagram Product Description The ASM2P2310A is a high-performance, low-skew clock buffer that operates up to 200MHz. Two banks of five outputs each provide low-skew copies of CLK. After power up, the default state of the outputs is low regardless of the state of the control pins. For normal operation, the outputs of bank 1Y[0:4] or 2Y[0:4] can be placed in a low state when the control pins (1G or 2G, respectively) are held low and a negative clock edge is detected on the CLK input. The outputs of bank 1Y[0:4] or 2Y[0:4] can be switched into the buffer mode when the control pins (1G and 2G) are held high and a negative clock edge is detected on the CLK input. The device operates in a 2.5V and 3.3V environment. The built-in output enable glitch suppression ensures a synchronized output enable sequence to distribute full period clock signals. The ASM2P2310A is characterized for operation from -40°C to 85°C.
