2.5 GHz D-type — what the clock frequency buys the design
The Microchip SY55852UKG is a single-bit D-type flip-flop with a rated clock frequency of 2.5 GHz, making it suitable for high-speed data retiming, clock distribution, and serializer-deserializer (SERDES) interface buffering in telecom and datacom equipment. The positive-edge trigger and complementary outputs simplify differential signal paths. The wide supply range of 2.3V to 5.7V allows it to bridge 3.3V and 5V logic families without a level translator, though the quiescent current of 36 mA is a constant draw regardless of toggle rate — budget that into the rail.
Supply and temperature — industrial-grade flexibility
The 2.3V minimum supply means it can run from a 2.5V rail common in low-power FPGAs, while the 5.7V maximum covers legacy 5V TTL environments. The 10-MSOP package (3.00 mm width) is a compact footprint for dense PCBs, but the 36 mA quiescent current means the thermal dissipation at 85°C needs a quick check — the junction-to-ambient theta for MSOP-10 is around 150°C/W, so at 5.7V and 36 mA the power is 205 mW, keeping the die below 115°C even at ambient 85°C.
