DESCRIPTION
The SY89327L is a fully differential, high-speed translator
optimized to accept any logic standard from single-ended
TTL/CMOS to differential LVDS, HSTL, or CML and translate
it to LVPECL. Translation is guaranteed for speeds up to
2.5Gbps (2.5GHz toggle frequency). The SY89327L does
not internally terminate its inputs because different interfacing
standards have different termination requirements.
The SY89327L is a member of Micrel’s Precision Edge®
family of high-speed logic devices. This family features ultra-
small packaging, as well as high signal integrity and
operation at many different supply voltages.
All support documentation can be found on Micrel’s web
site at www.micrel.com.

Pin Function
Differential inputs: This input is the differential signal input to the device. This input
accepts AC- or DC-coupled signals as small as 100mV. External termination is required.
Please refer to the Input Interface Applicationssection for more details.
Positive power supply. Bypass with 0.1µF0.01µF low ESR capacitors.
Differential LVPECL Output: Terminate with 50to VCC2V. See Output Interface
Applicationssection. Output pair is 100k temperature compensated LVPECL compatible.
Ground: Ground pin and exposed pad must be connected to the same ground plane.
No connect.
FUNCTIONAL DESCRIPTION
Establishing Static Logic Inputs
Do not leave unused inputs floating. Tie either the true or
complement input to ground. A logic zero is achieved by
connecting the complement input to ground with the true
input floating. For a TTL input, tie a 2.5kresistor between
the complement input and ground. See Input Interface
section.
Input Levels
LVDS, CML, and HSTL differential signals may be
connected directly to the D inputs. Depending on the actual
worst case voltage seen, the SY8327L's performance varies
as per the following table:
Input Voltage
Range
0 to 2.4V
0 to VCC +0.3V
Minimum

Maximum
Translation Speed

For LVDS applications, only point-to-point interfaces are
supported. Due to the current required by the input structure
shown in Figure 1, multi-drop and multi-point architectures
are not supported.

Notes:
1. Permanent device damage may occur if the Absolute Maximum Ratingsare exceeded. This is a stress rating only and functional operation is not
implied at conditions other than those detailed in the operational sections of this data sheet. Exposure to the absolute maximum ratings conditions
for extended periods may affect device reliability.
2. The data sheet limits are not guaranteed if the device is operated beyond the operating ratings.
3. Package Thermal Resistance assumes exposed pad is soldered (or equivalent) to the devices' most negative potential on the PCB. ΨJB uses 4-layer
θJA in still-air unless otherwise stated.
4. The circuit is designed to meet the DC specifications shown in the above table after thermal equilibrium has been established.
