NOT RECOMMENDED FOR NEW DESIGNS SY54023AR
Low Voltage 1.2V/1.8V CML 2x2
Crosspoint Switch 3.2Gbps, 3.2GHz General Description
The SY54023AR is a fully differential, low voltage
1.2V/1.8V CML 2x2 Crosspoint. The SY54023AR can
process clock signals as fast as 3.2GHz 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
from a 2.5V driver) as small as 100mV (200mVpp)
without any level-shifting or termination resistor
networks in the signal path. For AC-coupled input
interface applications, an internal voltage reference is
provided to bias the VT pin. The outputs are 400mV
CML, with extremely fast rise/fall times guaranteed to be
less than 95ps.
The SY54023AR operates from a 2.5V В±5% core supply
and a 1.8V or 1.2V В±5% output supply and is
guaranteed over the full industrial temperature range (–
40°C to +85°C). The SY54023AR is part of Micrel’s
high-speed, Precision EdgeВ® product line.
