LVPECL FANOUT BUFFER
IDT85304-01
FEATURES:
• Five differential 3.3V LVPECL outputs
• Selectable differential CLK, xCLK, or LVPECL clock inputs
• CLK, xCLK pair can accept the following differential input levels:
LVDS, LVPECL, LVHSTL, SSTL, and HCSL
• PCLK, xPCLK supports the following input types: LVPECL, CML,
and SSTL
• Maximum output frequency: 650MHz
• Translates any single-ended input signal to 3.3V LVPECL levels
with resistor bias on xCLK input
• Output skew: 35ps (max.)
• Part-to-part skew: as low as 150ps
• Propagation delay: 2.1ns (max.)
• 3.3V operating supply
• Available in TSSOP package
DESCRIPTION:
The IDT85304-01 is a low skew, high performance 1-to-5 differential-to-
3.3VLVPECLclockgenerator-divider. Ithastwoselectableclockinputs. The
CLK/xCLKpaircanacceptmoststandarddifferentialinputlevels. ThePCLK/
xPCLKpaircanacceptLVPECL,CML,orSSTLinputlevels. Theclockenable
is internally synchronized to eliminate runt pulses on the outputs during
asynchronous assertion/deassertion of the clock enable pin.
