Anything-to-LVPECL/LVDS Translators
with Pin-Selectable Divide-by-Four
General Description
The MAX9377/MAX9378 are fully differential, high-
speed, low-jitter anything-to-LVPECL and anything-to-
LVDS translators, respectively, with a selectable
divide-by-four function. Low propagation delay and
high speed make them ideal for various high-speed
network routing and backplane applications at speeds
up to 2GHz in nondivide mode.
The MAX9377/MAX9378 accept any differential input
signal within the supply rails and with minimum ampli-
tude of 100mV. Inputs are fully compatible with the
LVDS, LVPECL, HSTL, and CML differential signaling
standards. The MAX9377 outputs are LVPECL and
have sufficient current to drive 50Ω transmission lines.
The MAX9378 outputs are LVDS and conform to the
ANSI EIA/TIA-644 LVDS standard.
The MAX9377/MAX9378 are available in 8-pin µMAX
packages and operate from a single +3.3V supply over
the -40°C to +85°C temperature range.
