Description

The SA8026 BICMOS device integrates programmable dividers, charge pumps and a phase comparator to implement a
phase-locked loop. The SA8026 is designed to operate from 3 NiCd cells, in pocket phones, with low current and nominal 3 V supplies.

The synthesizer SA8026 operates at VCO input frequencies up to 2.5 GHz. The synthesizer has fully programmable main, auxiliary and reference dividers. All divider ratios are supplied via a 3-wire serial programming bus.

Separate power and ground pins of SA8026 are provided to the analog and digital circuits. The ground leads should be externally short-circuited to prevent large currents flowing across the die and thus causing damage. VDDCP must be greater than or equal to VDD.

The charge pump current (gain)SA8026 is set by an external resistance at RSET pin. Passive loop filters could be used; the charge pump operates within a wide voltage compliance range to provide a wider tuning range.
