General Description

The SY58606U is a 2.5/3.3V, high-speed, fully differential 1:2 CML fanout buffer optimized to provide two identical output copies with less than 15 ps of skew and 100 fs _RMS of typical additive phase jitter. The SY58606U can process clock signals as fast as 3 GHz or data patterns up to 4.25 Gbps.

The differential input includes Microchip's unique, 3-lead input termination architecture that interfaces to LVPECL, LVDS, or CML differential signals, (AC- or DC-coupled) as small as 100 mV (200 mV PP ) without any level-shifting or termination resistor networks in the signal path. For AC-coupled input interface applications, an integrated voltage reference ( VREF-AC ) is provided to bias the V_T pin. The outputs are 400 mV CML, with extremely fast rise/fall times guaranteed to be less than 85 ps.

The SY58606U operates from a 2.5V ±5% supply or 3.3V ±10% supply and is guaranteed over the full industrial temperature range (-40°C to +85°C). For applications that require LVPECL or LVDS outputs, consider Microchip's SY58607U and SY58608U, 1:2 fanout buffers with 800 mV and 325 mV output swings respectively. The SY58606U is part of Microchip's high-speed, Precision Edge® product line.

4.0 PIN DESCRIPTIONS

The descriptions of the pins are listed in Table 4-1.

TABLE 4-1: PIN FUNCTION TABLE

Pin Number Symbol Description
1, 4 IN, /IN Differential Input: This input pair is the differential signal input to the device.Input accepts DC-coupled differential signals as small as 100 (200 mVPP). Each pin of this pair internally terminates with 50Ω to the VT pin. If the input swing falls below a certain threshold (typical 30 mV), the Fail Safe Input (FSI) feature will guarantee a stable output by latching the output to its last valid state. See the Input Interface Applications section.
2VTInput Termination Center Tap: Each side of the differential input pair terminates to the VT pin. This pin provides a center-tap to a termination network for maximum interface flexibility. See the Input Interface Applications section.
3VREF-ACReference Voltage: This output biases to VCC - 1.2V. It is used for AC-coupling inputs IN and /IN. Connect VREF-AC directly to the VT pin. Bypass with 0.01 μF low-ESR capacitor to VCC. Maximum sink/source current is ±1.5 mA. See the Input Interface Applications section.
5, 8,13, 16VCCPositive Power Supply: Bypass with 0.1 μF//0.01 μF low-ESR capacitors as close to the VCC pins as possible.
6, 7, 14, 15GND, Exposed padGround: Exposed pad must be connected to a ground plane that is the same potential as the ground pins.
9, 1011, 12/Q1, Q1/Q0, Q0CML Differential Output Pairs: Differential buffered copies of the input signal. The output swing is typically 400 mV. Unused output pair may be left floating with no impact on jitter. See the CML Output Termination section.

5.0 FUNCTIONAL DESCRIPTION

5.1 Fail-Safe Input (FSI)

The input includes a special fail-safe circuit to sense the amplitude of the input signal and to latch the outputs when there is no input signal present, or when the amplitude of the input signal drops sufficiently below 100 mV_PK ( 200 mV_PP ), typically 30 mV_PK . Maximum frequency of SY58606U is limited by the FSI function.

5.2 Input Clock Failure Case

If the input clock fails to a floating, static, or extremely low signal swing, then the FSI function will eliminate a metastable condition and guarantee a stable output. No ringing and no undetermined state will occur at the output under these conditions.

Note that the FSI function will not prevent duty cycle distortion in case of a slowly deteriorating (but still toggling) input signal. Due to the FSI function, the propagation delay will depend on rise and fall time of the input signal and on its amplitude. Refer to the Typical Performance Curves section for detailed information.

NOTES:

Note the following details of the code protection feature on Microchip devices:

• Microchip products meet the specification contained in their particular Microchip Data Sheet.
- Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions.
- There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip's Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
• Microchip is willing to work with the customer who is concerned about the integrity of their code.
- Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.”

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products. Attempts to break Microchip's code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
