DESCRIPTION

The SY58017U is a 2.5V/3.3V precision, high-speed, 2:1 differential MUX capable of handling clocks up to 7GHz and data up to 10.7Gbps.

The differential input includes Micrel's unique, 3-pin input termination architecture that allows customers to interface to any differential signal (AC- or DC-coupled) as small as 100mV without any level shifting or termination resistor networks in the signal path. The outputs are 50Ω source terminated CML, with extremely fast rise/fall times guaranteed to be less than 60ps.

The SY58017U operates from a 2.5V ±5% supply or a 3.3V ±10% supply and is guaranteed over the full industrial temperature range of -40°C to +85°C. For applications that require LVPECL outputs, consider the SY58018U or SY58019U Multiplexers with LVPECL outputs. The SY58017U is part of Micrel's high-speed, Precision Edge® product line.

All support documentation can be found on Micrel's web site at www.micrel.com.

PIN DESCRIPTION

Pin Number Pin	Name Pin Function
1, 2 IN0, /IN03, 4 IN1, /IN1	Differential Input: These input pairs are the differential signal inputs to the device. They accept differential AC- or DC-coupled signals as small as 100mV. Each pin of a pair internally terminates to a V_T pin through 50Ω. Note that these inputs will default to an indeterminate state if left open. Please refer to the “Input Interface Applications” section for more details.
16, 5 VT0, VT1	Input Termination	Center-Tap: Each side of the differential input pair terminates to a V T pin. The V_T0 and V_T1 pins provide a center-tap to a termination network for maximum interface flexibility. See “Input Interface Applications” section for more details.
6 SEL This	single-ended TTL	CMOS compatible input selects the inputs to the multiplexer. Note that this input is internally connected to a 25kΩ pull-up resistor and will default to a logic HIGH state if left open.
7	N	C No connect.
8, 13	VCC	Positive Power Supply: Bypass with 0.1μF||0.01μF low ESR capacitors. 0.01μF capacitor should be as close to V_CC pin as possible.
12, 9 Q, /Q Differential Outputs		This CML output pair is the output of the device. Normally terminate with 100Ω across Q and /Q. See “Output Interface Applications” section. It is a logic function of the IN0, IN1, and SEL inputs. Please refer to the “Truth Table” for details.
10, 11, 14, 15	GND, Exposed Pad	Ground. Ground pins and exposed pad must be connected to the same ground plane.

Notes:

1. Permanent device damage may occur if "Absolute Maximum Ratings" are 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 "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 device's most negative potential (GND) on the PCB. _JB uses 4-layer _JA in still-air measurement, 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. Includes current through internal 50Ω pull-ups.
7. V_IH (min) not lower than 1.2V.

Notes:

1. High-frequency AC parameters are guaranteed by design and characterization.
2. Input-to-input skew is the difference in time from and input-to-output in comparison to any other input-to-output. In addition, the input-input skew does not include the output skew.
3. Part-to-part 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.
4. RJ is measured with a K28.7 comma detect character pattern, measured at 2.5Gbps/3.2Gbps.
5. DJ is measured at 2.5Gbps/3.2Gbps, with both K28.5 and 2^23-1 PRBS pattern.
6. Cycle-to-cycle jitter definition: the variation of periods between adjacent cycles, T_n - T_n-1 where T is the time between rising edges of the output signal.
7. 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.
8. Crosstalk is measured at the output while applying two similar frequencies that are asynchronous with respect to each other at the inputs.
