SY54017R
Low Voltage 1.2V/1.8V CML 2:1 MUX
with Fail Safe Inputs, 3.2Gbps, 2.5GHz
General Description
The SY54017R is a fully differential, low voltage
1.2V/1.8V CML 2:1 MUX with Fail Safe Inputs. The
SY54017R can process clock signals as fast as 2.5GHz
or data patterns up to 3.2Gbps.
The differential input includes Micrelâs 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 CML, with
extremely fast rise/fall times guaranteed to be less than
95ps.
The SY54017R operates from a 2.5V ±5% core supply
and a 1.8V or 1.2V ±5% output supply and is
guaranteed over the full industrial temperature range
(â40°C to +85°C). The SY54017R is part of Micrelâs
high-speed, Precision Edge® product line.
