Microchip | SY100EP57VK4G-TR

The SY100EP57VK4G TR 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 replacementto the MC10/100EP57DT. The signal-path inputs (D0:D3) accept differential signals as low as 150 mVpk-pk. All I/O pins are 100K EP PECL/ECL logic compatible. AC–performance is guaranteed over the industrial –40°C to +85°C temperature range and 3.0 V to 5.5 V supply voltage range.

This device will operate in PECL/LVPECL or ECL/ LVECL mode. The SY100EP57 propagation delay is less than 520 ps, and the Select-to-valid output delay is less than 575 ps over temperature and voltage. For clock applications, the high-speed design combined with an extremely fast rise/fall time of less than 220 ps produces a toggle frequency as high as 3 GHz (400 mVpk-pk swing). Two VBB output reference pins (approx equal to VCC–1.4 V) 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.
