1. Description
The ATR2730 is a monolithically integrated L-band down-converter circuit fabricated
with Atmel®’s advanced UHF5S technology. This IC covers all functions of an L-band
down-converter in a DAB receiver. The device 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 synthesizer unit. The
frequency synthesizer 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.
