ZERO DELAY BUFFER
DESCRIPTION:
The CSP2510C 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 CSP2510C
operates at 3.3V.
One bank of ten outputs provide low-skew, low-jitter copies of CLK.
Output signal duty cycles are adjusted to 50 percent, independent of the
duty cycle at CLK. The outputs can be enabled or disabled via the control
G 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 CSP2510C does not require
external RC networks. The loop filter for the PLL is included on-chip,
mnimzing component count, board space, and cost.
Because it is based on PLL circuitry, the CSP2510C 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 the test purposes by strapping AV
DD
to ground.
The CSP2510C is specified for operation from0°C to +85°C. This
device is also available (on special order) in Industrial temperature range
(-40°C to +85°C). See ordering information for details.
