DESCRIPTION
The SY100EP57V is a high-speed, low-skew, fully differential PECL/ECL 4:1 multiplexer in a 20-pin TSSOP package. This device is a pin-for-pin, plug-in replacement to the MC10/100EP57DT. The signal-path inputs (D0:D3) accept differential signals as low as 150mVpk-pk. All I/O pins are 100K EP PECL/ECL logic compatible. AC-performance is guaranteed over the industrial -40C to +85C temperature range and 3.0V to 5.5V supply voltage range. This device will operate in PECL/LVPECL or ECL/ LVECL mode. The SY100EP57 propagation delay is less than 520ps, and the Select-to-valid output delay is less than 575ps over temperature and voltage. For clock applications, the high-speed design combined with an extremely fast rise/fall time of less than 220ps produces a toggle frequency as high as 3GHz (400mVpk-pk swing). Two VBB output reference pins (approx equal to VCC-1.4V) are available for AC-coupled or single-ended applications. The SY100EP57V is part of Micrel's high-speed, Precision Edge timing and distribution family. For applications that require a different I/O combination, consult the Micrel website at www.micrel.com, and choose from a comprehensive product line of high-speed, low skew fanout buffers, translators, and clock dividers.

PIN DESCRIPTION
Pin D0: D3 /D0: /D3 Pin Number 2, 4, 6, 8 3, 5, 7, 9 Function Input Channels 0-3 PECL/ECL differential signal inputs. Multiplexing of these 4 differential inputs is controlled by SEL0, SEL1. The signal inputs include internal 75k pull-down resistors. Default condition is LOW when left floating. The input signal should be terminated externally. See "Termination" section Negative Power Supply: For PECL/LVPECL applications, connect to Ground. Both VEE pins must be connected together, externally on the PCB, for proper operation. Reference output voltage. This reference is typically used to bias the unused inverting input for single-ended input applications, or as the termination point for AC-coupled differential input applications. VBB reference value is approximately VCC -1.4V, and tracks VCC 1:1. Maximum sink/ source capability for each VBB reference pin is 0.50mA. For single ended PECL inputs, connect to the unused input through a 50 resistor. Decouple the VBB pin with a 0.01F capacitor. For PECL/ LVPECL inputs, the decoupling capacitor is connected to VCC, since PECL signals are referenced to VCC. Leave floating if not used. 100KEP PECL/ECL compatible differential output. PECL/ECL termination is with a 50 resistor to VCC -2V. Unused single-ended outputs must have a balanced load. For AC-coupled applications, the output stage emitter follower must have a DC current path to ground. See "Termination" section. 100KEP PECL/ECL compatible 4:1 MUX select control. See "MUX Select Truth Table." Each pin includes an internal 75k pull-down resistor. Default condition when left floating is LOW. Positive Power Supply. All VCC pins must be connected to the same power supply externally. Bypass with 0.1F//0.01F low ESR capacitors.

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 RATlNG conditions for extended periods may affect device reliability. Due to the limited drive capability, the VBB reference should only be used for inputs from the same package device (i.e., do not sue for other devices).
