SY58020U

6GHz, 1:4 CML Fanout Buffer/Translator

with Internal I/O Termination

Features

General Description

• Precision 1:4, 400mV CML fanout buffer

• Guaranteed AC performance over temperature/voltage:

− > 6GHz f_MAXclock

The SY58020U is a 2.5V/3.3V precision, high-speed, fully

differential 1:4 CML fanout buffer. Optimized to provide

four identical output copies with less than 15ps of skew

and 27fs_RMSof typical additive phase jitter, the SY58020U

can process clock signals as fast as 6GHz.

− < 60ps t_r/ t_ftimes

− < 250ps t_pd

The differential input includes Micrel’s unique, 3-pin input

termination architecture that interfaces to differential

LVPECL, LVDS, and CML signals (AC- or DC-coupled) as

small as 100mV without any level-shifting or termination

resistor networks in the signal path. For AC-coupled input

interface applications, an on-board output reference

voltage (V_REF-AC) is provided to bias the V_Tpin. The outputs

are optimized to drive 400mV typical swing into 50Ω loads,

with extremely fast rise/fall times guaranteed to be less

than 60ps.

− < 15ps max. skew

• Low-jitter performance:

− 27fs_RMStypical additive phase jitter

• Accepts an input signal as low as 100mV

• Unique patented input termination and V_Tpin accepts

DC-coupled and AC-coupled differential inputs:

LVPECL, LVDS, and CML

• 50Ω source terminated CML outputs

• Power supply 2.5V ±5% and 3.3V ±10%

• Industrial temperature range: –40°C to +85°C

• Available in 16-pin (3mm x 3mm) QFN package

The SY58020U operates from a 2.5V ±5% supply or 3.3V

±10% supply and is guaranteed over the full industrial

temperature range (–40°C to +85°C). For applications that

require LVPECL outputs, consider the SY58021U or

SY58022U 1:4 fanout buffer with 800mV and 400mV

output swing, respectively. The SY58020U is part of

Micrel’s high-speed, Precision Edge^®product line.
