50–150 MHz 1:9 SDRAM clock driver
PCK2509SA
FEATURES
• Phase-Locked Loop Clock distribution for
PC100/PC133 SDRAM applications
• JEDEC compliant operation—PLL reamins locked when outputs
are disabled.
adjusted to 50 percent, independent of the duty cycle at CLK. Each bank of outputs can be enabled or disabled separately via the control (1G and 2G) inputs. When the G inputs are high, the outputs switch in phase and frequency with CLK; when the G inputs are low, the outputs are disabled to the logic–low state.
