General Description
The ICS2509C
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
ICS2509C
operates at 3.3V VCC
and drives up to nine clock loads.
Features
Meets or exceeds PC133 registered DIMM
specification 1.1
Spread Spectrum Clock Compatible
Distributes one clock input to one bank of five and one
bank of four outputs
Separate output enable(OEA,OEB) for each output bank
Operating frequency 25 MHz to 175 Mhz
External feedback input (FBIN) terminal is used to
synchrionize the outputs to the clock input
No external RC network required
Operates at 3.3V Vcc
Plastic 24-pin 173mil TSSOP package

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
ICS2509C
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
ICS2509C
can be
use as low skew fanout clock buffer device. The
ICS2509C
comes in 24 pin 173mil Thin Shrink Small-Outline package
(TSSOP) package.
