3.2Gbps Precision, LVDS Buffer with
Internal Termination and Fail Safe Input General Description
The SY58605U is a 2.5V, high-speed, fully differential
LVDS buffer optimized to provide less than 10pspp total
jitter. The SY58605U can process clock signals as fast
as 2GHz or data patterns up to 3.2Gbps.
The differential input includes MicrelвЂ™s unique, 3-pin
input termination architecture that interfaces to LVPECL,
LVDS or CML differential signals, (AC-or DC-coupled)
as small as 100mV (200mVpp) without any level-shifting
or termination resistor networks in the signal path. For
AC-coupled input interface applications, an integrated
voltage reference (VREF-AC) is provided to bias the VT pin.
The output is 325mV LVDS, with rise/fall times
guaranteed to be less than 100ps.
The SY58605U operates from a 2.5V В±5% supply and is
guaranteed over the full industrial temperature range
(вЂ“40В°C to +85В°C). For applications that require CML or
LVPECL outputs, consider MicrelвЂ™s SY58603U and
SY58604U, buffers with 400mV and 800mV output
swings respectively. The SY58605U is part of MicrelвЂ™s
