SP8904 is a very high-speed low-power prescaler for professional applications. The dividing elements are static D type flip flops and therefore allow operation down to DC if the drive signal is a pulse waveform with fast risetime. The output stage has a differential current output and provides a direct drive into a 50 ohm load.
The SP8904 (MP) is a high‑speed, low‑power prescaler designed for professional applications. It uses static D‑type flip‑flops, allowing operation down to DC with square‑wave inputs, and provides a differential current output that can directly drive a 50 Ω load.
Key features include 5 V single‑supply operation, typical power dissipation of 350 mW, phase‑noise performance better than 2140 dBc/Hz at 1 kHz, and support for input frequencies up to 5 GHz. The device is supplied in surface‑mount plastic packages and is covered by the usual absolute‑maximum ratings for voltage, temperature and current.
