3.3V Phase-Lock Loop Clock Driver
Pin Configuration
The ICSVF2509B is a high performance, low skew, low
jitter clock driver.It uses a phase lock loop (PLL) technology
to align, in both phase and frequency, the CLKIN signal
with the CLKOUT signal. It is specifically designed for use
with synchronous SDRAMs. The ICSVF2509B operates
at 3.3V VCC and drives up to nine clock loads.
One bank of five outputs and one bank of four outputs
provide nine low-skew, low-jitter copies of CLKIN. Output
signal duty cycles are adjusted to 50 percent, independent
of the duty cycle at CLKIN. Each bank of outputs can be
enabled or disabled separately via control (OEA and OEB)
inputs. When the OE inputs are high, the outputs align in
phase and frequency with CLKIN; when the OE inputs are
low, the outputs are disabled to the logic low state.
The ICSVF2509B does not require external RC filter
components.The loop filter for the PLL is included on-chip,
minimizing component count, board space, and cost.The
buffer mode shuts off the PLL and connects the input
directly to the output buffer. This buffer mode, the
ICSVF2509B can be use as low skew fanout clock buffer
device. The ICSVF2509B comes in 24 pin 173mil Thin
Shrink Small-Outline package (TSSOP) package.
