ICS8536-01
Differential-to-3.3V, 2.5V LVPECL Fanout Buffer
DATA SHEET
GENERAL DESCRIPTION
The ICS8536-01 is a low skew, high performance 1-to-6
Selectable Crystal, Single-Ended, or Differential Input-to-
3.3V, 2.5V LVPECL Fanout Buffer. The ICS8536-01 has
selectable crystal, single ended or differential clock inputs.
The single ended clock input accepts LVCMOS or LVTTL
input levels and translates them to LVPECL levels. The
CLK1, nCLK1 pair can accept most standard differential
input levels. The output enable is internally synchronized to
eliminate runt pulses on the outputs during asynchronous
assertion/deassertion of the clock enable pin.
Guaranteed output and part-to-part skew characteristics
make the ICS8536-01 ideal for those applications demanding
well defined performance and repeatability.
FEATURES
• Six 3.3V, 2.5V LVPECL outputs
• Selectable crystal oscillator, differential CLK1, nCLK1 pair
or LVCMOS/LVTTL clock input
• CLK1, nCLK pair can accept the following differential
input levels: LVPECL, LVDS, LVHSTL, SSTL, HCSL
• Maximum output frequency: 700MHz
• Crystal frequency range: 12MHz - 40MHz
• Output skew: 55ps (maximum) CLK1, nCLK1 @ 3.3V
• Part-to-part skew: 450ps (maximum)
• Additive phase jitter, RMS: 0.19ps (typical)
• Full 3.3V or 2.5V supply mode
• 0°C to 70°C ambient operating temperature
• Available in lead-free (RoHS 6) packages
