GENERAL DESCRIPTION

The ICS8701 is a low skew, ÷1, ÷2 Clock Generator and a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. The low impedance LVCMOS outputs are designed to drive 50Ω series or parallel terminated transmission lines. The effective fanout can be increased from 20 to 40 by utilizing the ability of the outputs to drive two series terminated lines.

FEATURES

• 20 LVCMOS outputs, 7Ω typical output impedance

• 1 LVCMOS clock input

• Maximum output frequency up to 250MHz

• Bank enable logic allows unused banks to be disabled in reduced fanout applications

• Output skew: 250ps (maximum)

• Part-to-part skew: 600ps (maximum)

• Bank skew: 200ps (maximum)

• Multiple frequency skew: 300ps (maximum)

• 3.3V or mixed 3.3V input, 2.5V output operating supply modes

• 0°C to 70°C ambient operating temperature

• Other divide values available on request
