Yamaha YMF289
The Yamaha YMF289 is a low-power version of the YMF262 OPL3 FM synthesizer IC. It is designed for low-power applications such as laptops and PCMCIA sound cards. It was used in some Sound Blaster 16 sound cards made by Creative Technology. The YMF289B is paired with a YAC513 or YAC516 companion floating-point DAC chip.
The YMF289 is fully register-compatible with and retains the feature-set of the YMF262, with a number of differences:[1]
- Supports 5 or 3.3 volt operation.
- 44100 Hz (44.1 kHz) output sample rate.
- A power-down mode is added.
Tone-wise, the YMF289's output is very similar to the YMF262's, albeit exhibiting some artifacts from the 49.7 kHz -> 44.1 kHz re-sampling process.
