GENERAL DESCRIPTION
FEATURES
The ICS8752 is a low voltage, low skew
• Fully integrated PLL
,&6
LVCMOS clock generator and a member of
• 8 LVCMOS outputs, 7Ω typical output impedance
HiPerClockS™
the HiPerClockS™ family of High Performance
Clock Solutions from ICS. With output fre-
quencies up to 240MHz, the ICS8752 is targeted
• Selectable LVCMOS CLK0 or CLK1 inputs for
redundant clock applications
for high performance clock applications. Along with a fully in-
tegrated PLL, the ICS8752 contains frequency configurable
outputs and an external feedback input for regenerating clocks
with “zero delay”.
• Input/Output frequency range: 18.33MHz to 240MHz
at VCC = 3.3V ± 5%
• VCO range: 220MHz to 480MHz
Dual clock inputs, CLK0 and CLK1, support redundant clock
applications. The CLK_SEL input determines which reference
clock is used. The output divider values of Bank A and B are
controlled by the DIV_SELA0:1, and DIV_SELB0:1, respectively.
• External feedback for “zero delay” clock regeneration
• Cycle-to-cycle jitter: 75ps (maximum),
(all outputs are the same frequency)
• Output skew: 100ps (maximum)
For test and system debug purposes, the PLL_SEL input
allows the PLL to be bypassed. When HIGH, the MR/nOE
input resets the internal dividers and forces the outputs to
the high impedance state.
• Bank skew: 55ps (maximum)
• 3.3V or 2.5V supply voltage
• 0°C to 70°C ambient operating temperature
• Industrial temperature information available upon request
• Functionally compatible with MPC952 in some applications
The low impedance LVCMOS outputs of the ICS8752 are
designed to drive terminated transmission lines. The effec-
tive fanout of each output can be doubled by utilizing the
ability of each output to drive two series terminated trans-
mission lines.
