The SY58051U is an ultra-fast, low jitter universal logic
gate with a guaranteed maximum data or clock throughput
of 10.7Gbps or 7GHz, respectively. This AnyGate
differential logic device will produce many logic functions of
two Boolean variables, such as AND, NAND, OR, NOR,
DELAY, or NEGATION.
The SY58051U differential inputs include a unique,
internal termination design that allows access to the
termination network through a V
T
pin. This feature allows
the device to easily interface to different logic standards,
both AC- and DC-coupled without external resistor-bias and
termination networks. The result is a clean, stub-free, low-
jitter interface solution. The differential CML output is
optimized for 50
environments with internal 50
source
termination and a 400mV output swing.
The SY58051U operates from a 2.5V or 3.3V supply,
and is guaranteed over the full industrial temperature range
(40
C to +85
C). The SY58051U is part of a Micrel's
Precision EdgeTM product family.
All support documentation can be found on Micrel's web
site at www.micrel.com.

Notes:
1. Permanent device damage may occur if the ratings in the "Absolute Maximum Ratings" section are exceeded. This is a stress rating only and
functional operation is not implied for conditions other than those detailed in the operational sections of this data sheet. Exposure to 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. Due to the limited drive capability use for input of the same package only.
4. Package thermal resistance assumes exposed pad is soldered (or equivalent) to the devices most negative potential on the PCB.
JB
uses 4-layer
JA
in still-air, unless otherwise stated.
5. The circuit is designed to meet the DC specifications shown in the above table after thermal equilibrium has been established.
6. Due to the internal termination (see Figure 1a) the input current depends on the applied voltages at A, /A and V
TA
inputs, the B, /B and V
TB
inputs or
the S, /S and V
TS
inputs. Do not apply a combination of voltages that causes the input current to exceed the maximum limit!

Notes:
7. The circuit is designed to meet the DC specifications shown in the above table after thermal equilibrium has been established.
8.
Measured with 100mV input swing. See "Timing Diagrams" section for definition of parameters. High-frequency AC parameters are
guaranteed by design and characterization.
9.
Skew is defined for two parts with identical power supply voltages at the same temperature and with no skew of the edges at the respective inputs.
10. Random jitter is measured with a K28.7 comma detect character pattern, measured at 2.5Gbps/3.2Gbps.
11. Deterministic jitter is measured at 2.5Gbps/3.2Gbps with both K28.5 and 2
23
1 PRBS pattern.
12. Cycle-to-cycle jitter definition: the variation of periods between adjacent cycles, T
n

n1
where T is the time between rising edges of the output
signal.
13. Total jitter definition: with an ideal clock input of frequency
f
MAX
, no more than one output edge in 10
12
output edges will deviate by more than the
specified peak-to-peak jitter value.
