2.5Gbps, +3.3V Clock and Data Retiming ICs
with Vertical Threshold Adjust
General Description
The MAX3877/MAX3878 are compact, low-power clock
recovery and data retiming ICs for 2.488Gbps SONET/
SDH applications. The fully integrated phase-locked
loop (PLL) recovers a synchronous clock signal from
the serial NRZ data input, which is retimed by the
recovered clock. An additional 2.488Gbps serial input
is available for system loopback diagnostic testing, or
this input can be connected to a 155MHz reference
clock to maintain a valid clock output in the absence of
data transitions. The MAX3877/MAX3878 provide verti-
cal threshold and phase-adjust control to optimize sys-
tem BER in DWDM applications.
These devices provide both loss-of-lock (LOL) and
loss-of-signal (LOS) monitors. Differential CML outputs
are provided for both clock and data signals on the
MAX3877, and differential PECL outputs are provided
for clock and data signals on the MAX3878.
The MAX3877/MAX3878 are designed for both section-
regenerator and terminal-receiver applications in OC-
48/STM-16 transmission systems. Their jitter performance
exceeds all of the SONET/SDH specifications. These
devices operate from a single +3.0V to +3.6V supply over
a -40°C to +85°C temperature range. Typical power con-
sumption is only 540mW with a +3.3V supply (MAX3878).
They are available in a 32-pin TQFP-EP package with an
exposed pad, as well as in die form.
