description

The CDC2510 is a high-performance, low-skew, low-jitter, phase-lock loop (PLL) clock driver. It uses a PLL to

precisely align, in both frequency and phase, the feedback (FBOUT) output to the clock (CLK) input signal. It

is specifically designed for use with synchronous DRAMs. The CDC2510 operates at 3.3-V V

integrated series-damping resistors that make it ideal for driving point-to-point loads.

and provides

One bank of ten outputs provide ten low-skew, low-jitter copies of CLK. Output signal duty cycles are adjusted

to 50 percent, independent of the duty cycle at CLK. All outputs can be enabled or disabled via a single output

enable input. When the G input is high, the outputs switch in phase and frequency with CLK; when the G input

is low, the outputs are disabled to the logic-low state.

Unlike many products containing PLLs, the CDC2510 does not require external RC networks. The loop filter

for the PLL is included on-chip, minimizing component count, board space, and cost.

Because it is based on PLL circuitry, the CDC2510 requires a stabilization time to achieve phase lock of the

feedback signal to the reference signal. This stabilization time is required, following power up and application

of a fixed-frequency, fixed-phase signal at CLK, as well as following any changes to the PLL reference or

feedback signals. The PLL can be bypassed for test purposes by strapping AV

to ground.

The CDC2510 is characterized for operation from 0°C to 70°C.
