ICS873991

LOW VOLTAGE, LVCMOS/

LVPECL-TO-LVPECL/ECL CLOCK GENERATOR

FEATURES

GENERAL DESCRIPTION

• 14 differential LVPECL outputs

The ICS873991 is a low voltage, low skew, 3.3V LVPECL

or ECL Clock Generator. The ICS873991 has two selectable

• Selectable differential LVPECL orTEST_CLK inputs

clock inputs. The PCLK, nPCLK pair can accept an LVPECL

input and the TEST_CLK pin can accept a LVCMOS or LVTTL • PCLK, nPCLK can accept the following input levels:

input. This device has a fully integrated PLL along with

frequency configurable outputs. An external feedback input

and output regenerates clocks with “zero delay”.

LVPECL, CML, SSTL

• TEST_CLK accepts the following input levels:

LVCMOS, LVTTL

The four independent banks of outputs each have their

own output dividers, which allow the device to generate a

multitude of different bank frequency ratios and output-to-

input frequency ratios. The output frequency range is 25MHz

to 400MHz and the input frequency range is 6.25MHz to

125MHz. The PLL_SEL input can be used to bypass the PLL

for test and system debug purposes. In bypass mode, the input

clock is routed around the PLL and into the internal output

dividers.

• Input frequency range: 6.25MHz to 125MHz

• Output frequency: 400MHz (maximum)

• VCO range: 200MHz to 800MHz

• Output skew: 250ps (maximum)

• Cycle-to-cyle jitter: 50ps (typical)

• LVPECL mode operating voltage supply range:

V_CC= 3.135V to 3.465V, V_EE= 0V

The ICS873991 also has a SYNC output which can be used for

system synchronization purposes. It monitors Bank A and Bank

C outputs for coincident rising edges and signals a pulse per the

timing diagrams in this data sheet.This feature is used primarily

in applications where Bank A and Bank C are running at different

frequencies, and is particularly useful when they are running at

non-integer multiples of each other.

• ECL mode operating voltage supply range:

V_CC= 0V, V_EE= -3.465V to -3.135V

• 0°C to 70°C ambient operating temperature

• Industrial temperature available upon request

• Lead-Free package fully RoHS compliant

Example Applications:

1. Line Card Multiplier: Multiply 19.44MHz from a back-plane

to 77.76MHz on the line card ASIC and Serdes.

PIN ASSIGNMENT

2. Zero Delay Buffer: Fan out up to thirteen 100MHz copies

from a reference clock to multiple processing units on an

embedded system.
