ASM2P2310A
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.
