Description

The U2730B-N is a monolithically integrated L-band down-converter circuit fabricated with Atmel's advanced UHF5S technology. U2730B-N covers all functions of an L-band down-converter in a DAB receiver. The U2730B-N includes a gain-controlled amplifier, a gain-controlled mixer, an output buffer, a gain control block, a power save function for the analog part, an L-band oscillator and a complete frequency syntheziser unit. The frequency syntheziser block consists of a reference oscillator/buffer, a reference divider, an RF divider, a tri-state phase detector, a loop filter amplifier, a lock detector, a programmable charge pump, a test interface and a control interface.
