The SY100EP56V is a high-speed, low-skew, fully differential Dual PECL/ECL 2:1 multiplexer. This device is a pin-for-pin, plug-in replacement to the MC10/100EP56DT. Two separate 2:1 multiplexers (Channel 0 and Channel 1) with dedicated select control pins (SEL0 and SEL1) are implemented in a 20-pin TSSOP package. The signal-path inputs (D0a, D0b and D1a, D1b) accept differential signals as low as 150mV pk-pk. For applications that require common select control for both channels A & B, a common select pin (COM_SEL) is available. All I/O pins are 100k PECL/ECL logic compatible. AC–performance is guaranteed over the industrial –40°C to +85°C temperature range and 3.0V to 5.5V supply voltage range. This device will operate in PECL/LVPECL or ECL/ LVECL mode. The 500ps max (400 typ) propagation delay is matched for all signal and logic select paths: D-to-QOUT, SEL-to-QOUT, and COM_SEL-to-QOUT. Two VBB output reference pins (approx equal to VCC –1.4V) are available for AC–coupled or single-ended applications. The SY100EP56V 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.
