Datasheet Summary
YOUDA INTEGRATED CIRCUIT
FM RECEIVER CIRCUIT FOR BATTERY SUPPLY
- YD9088
DESCRIPTION
The YD9088 is a bipolar integrated circuit for use in mono portable and pocket radios. It is used when a minimum of peripheral ponents (of small dimensions and low costs) is important. The circuit contains a frequency-locked-loop (FLL) system with an intermediate Frequency (IF) of about 70kHz. Selectivity is achieved by active RC-filters. De-tuning related to the IF and too weak input signals is suppressed by the mute circuit.
