The SY10/100E107 offer five 2-input XOR/XNOR gates and are designed for use in new, high-performance ECL systems. The E107 also features a function output, F, which is the OR of all five XOR gate outputs, while F is the NOR. Both true and complementary outputs are provided.

The MIC5246 is a low-noise LDO produced by Micrel, which has ultra-low dropout and high precision. It is suitable for applications with high requirements for power stability.

The SY10E107 and SY100E107 are quint 2-input XOR/XNOR gates with OR/NOR function outputs. Both true and complementary outputs are provided.

The SY10/100E104 are quint 2-input AND/NAND gates designed for use in new, high-performance ECL systems. The E104 also features a function output, F, which is the OR of all five AND gate outputs, while F is the NOR. Both true and complementary outputs are provided.

The SY10E101 and SY100E101 are quad 4-input OR/NOR gates designed for use in new, high-performance ECL systems. The E101 features both true and complementary outputs.

The SY10/100E016 are high-speed synchronous, presettable and cascadable 8-bit binary counters designed for use in new, high-performance ECL systems.

This datasheet provides detailed information on the MIC5219 500mA-Peak Output LDO Regulator, including its high peak output current capability, very low dropout voltage, better than 1% output voltage accuracy, 10mV typical dropout at light loads, less than 500mV maximum dropout at full load, 500mA peak output rating, continuous output current limited only by package and layout, CMOS or TTL compatible signal to enable or shut down the MIC5219, power consumption drops to nearly zero when disabled, minimized dropout ground current to help prolong battery life, reverse battery protection, current limiting, overtemperature shutdown, and low noise performance with an ultra-low-noise option.

The SY89421V is a digital Phase Locked Loop based on Micrel-Synergy's differential PLL technology. It is capable of operating in the 30MHz to 560MHz reference input frequency range, and up to 2000MHz with the HFIN input and an external VCO. Use of a phase-frequency detector results in excellent PLL locking and tracking characteristics. Error correction voltages are generated by the detector if either phase or frequency deviations occur. The VCO has a frequency range covering more than a 2:1 ratio from 480MHz to 1120MHz. Feedback for the loop is realized by connecting FOUT, FOUT to FIN, FIN by means of external circuitry. This allows the flexibility of inserting additional circuitry off-chip in the feedback paths, such as an additional divider and/or buffer. Pulldown resistors are required for the FOUT and FOUT pins. High frequency inputs HFIN, HFIN and corresponding outputs HFOUT, HFOUT are featured for use with external components such as an active loop filter and a high frequency VCO. Select pins S1 and S2 are used to program the N divider for optimum VCO operation, in other words with the VCO in the center of its range. Select pin S3 allows bypassing the N divider enabling the PLL to output the VCO directly. Select pin S4 is used to select off-chip or on-chip VCO. Select pin S5 enables the divide-by-two prescaler, which is useful in frequency doubling applications. All Select pins are TTL compatible.
