The SY55852U is a flip-flop used to synchronize data to a clock. Its differential output will reproduce and remember the value on its input at the rising edge of the clock. In addition, an asynchronous, level sensitive reset is provided. For a synchonous reset, the SY55851U AnyGate® can be used.SY55852U inputs can be terminated with a single resistor between the true and complement pins of a given input.The SY55852U is a member of Micrel's SuperLite™ family of high-speed CML logic. This family features very small packaging and 2.3V to 5.7V operation.

The SY55855V is a fully differential, CML/PECL/LVPECL-to-LVDS translator. It achieves LVDS signaling up to 1.5Gbps, depending on the distance and the characteristics of the media and noise coupling sources. LVDS is intended to drive 50Ω impedance transmission line media such as PCB traces, backplanes, or cables.SY55855V inputs can be terminated with a single resistor between the true and the complement pins of a given input.The SY55855V is a member of Micrel's new SuperLite™ family of high-speed logic devices. This family features very small packaging, high signal integrity, and operation at many different supply voltages.

The SY55857L is a fully differential, high-speed dual translator optimized to accept any logic standard from single-ended TTL/CMOS to differential LVDS, HSTL, or CML and translate it to LVPECL. Translation is guaranteed for speeds up to 2.5Gbps (2.5GHz toggle frequency). The SY55857L does not internally terminate its inputs, as different interfacing standards have different termination requirements.

The SY55858U is a low-voltage, high-speed dual 2 x 2 crosspoint switch with a flexible input that accepts CML or PECL, and a 50Ω compatible differential CML (currentmode logic) output. The non-blocking design allows any input to connect to any output. Varying the state of the select inputs allows SY55858U to be used in backup, fault tolerant, protection and backplane distribution applications.The signal inputs (DA0-1 and DB0-1) have a unique internal termination design that allows access to the termination network through VT pins. This feature allows the device to easily interface to other logic standards such as AC-coupled or DC-coupled PECL/LVPECL signals. For applications that require a single-channel 2x2 crosspoint, consider the SY55854.

The SY56011R is a fully differential, low voltage 1.2V/1.8V/2.5V CML 1:2 Fanout Buffer with input equalization. The SY56011R can process clock signals as fast as 4.5GHz or data patterns up to 6.4Gbps.The differential input includes Micrel’s unique, 3-pin input termination architecture that interfaces to CML differential signals, without any level-shifting or termination resistor networks in the signal path. The differential input can also accept AC-coupled LVPECL and LVDS signals. Input voltages as small as 200mV (400mVpp) are applied before the 9", 18", or 27" FR4 transmission line. For AC-coupled input interface applications, an internal voltage reference is provided to bias the VT pin. The outputs are CML, with extremely fast rise/fall times guaranteed to be less than 80ps.The SY56011R operates from a 2.5V ±,5% core supply and a 1.2V, 1.8V or 2.5V ±5% output supply and is guaranteed over the full industrial temperature range (-40°C to +85°C).
