Low Voltage, Low Skew
3.3V LVPECL Clock Generator
8732-01
Data Sheet
GENERAL DESCRIPTION
The 8732-01 is a low voltage, low skew, 3.3V LVPECL Clock
Generator. The 8732-01 has two selectable clock inputs. The
CLK0, nCLK0 pair can accept most standard differential input
levels.The single ended clock input accepts LVCMOS or LVTTL
input levels. The 8732-01 has a fully integrated PLL along with
frequency configurable outputs. An external feedbackinput and
outputs regenerate clocks with “zero delay”.
The 8732-01 has multiple divide select pins for each bank of
outputs along with 3 independent feedback divide select pins
allowing the 8732-01 to function both as a frequency multiplier
and divider. The PLL_SEL input can be usedto bypass the
PLL for test and system debug purposes.In bypass mode,
the input clock is routed around the PLLand into the internal
output dividers.
Features
Ten differential 3.3V LVPECL outputs
Selectable differential CLK0, nCLK0 or
LVCMOS/LVTTL CLK1 inputs
CLK0, nCLK0 supports the following input types:
LVPECL, LVDS, LVHSTL, SSTL, HCSL
CLK1 accepts the following input levels:
LVCMOS or LVTTL
Maximum output frequency: 350MHz
VCO range: 250MHz to 700MHz
External feedback for “zero delay” clock regeneration
with configurable frequencies
Cycle-to-cycle jitter: CLK0, nCLK0, 50ps (maximum)
CLK1, 80ps (maximum)
Output skew: 150ps (maximum)
Static phase offset: -150ps to 150ps
Lead-Free package fully RoHS compliant
