SY58604U
3.2Gbps Precision, LVPECL Buffer with
Internal Termination and Fail Safe Input General Description
The SY58604U is a 2.5/3.3V, high-speed, fully
differential LVPECL buffer optimized to provide only
108fsRMS phase jitter. The SY58604U can process clock
signals as fast as 2.5GHz or data patterns up to
3.2Gbps.
The differential input includes Micrel’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 800mV LVPECL, with extremely fast
rise/fall times guaranteed to be less than 110ps.
The SY58604U operates from a 2.5V В±5% supply or
3.3V В±10% supply and is guaranteed over the full
industrial temperature range (–40°C to +85°C). For
applications that require CML or LVDS outputs, consider
the SY58603U and the SY58605U, buffers with 400mV
and 325mV output swings respectively. The SY58604U …
