Cirrus Logic Charges Into Low-Power Digital Audio Applications With Highly Integrated Mixed-Signal Codec IC; CS42L51 Delivers Su

Business Wire
Targeting new growth segments for analog integrated circuits (ICs),
Cirrus Logic Inc. (Nasdaq:CRUS) has introduced a new highly
integrated, low-power stereo codec for portable audio applications.
The CS42L51 is the first in a new line of products focused on
analog and mixed signal ICs for power-sensitive, battery-operated
applications such as HDD and flash-based music players, personal
media players, mini-disc players/recorders, PDAs, smart phones,
digital camcorders and digital voice recorders. The CS42L51
delivers excellent analog audio performance while providing system
designers with a solution that improves battery life, reduces end
product form factors and simplifies the recording and playback of
digital audio. The CS42L51's key distinction against competitive IC
products is that it can operate from a single 1.8V power supply for
low power consumption, yet deliver plenty of power -- 46mW -- into
stereo 16 ohm headphones for a great listening experience for
consumers. By generating its own on-chip negative power supply
voltage, the CS42L51 provides ground-centered outputs, which
eliminate costly, space-consuming DC-blocking capacitors. The
elimination of these capacitors not only reduces the implementation
cost but it also greatly simplifies product design and saves
valuable space on circuit boards. "We are excited about the value
this new codec will provide to our customers due to its small form
factor and elimination of expensive passive components, all while
operating from a single 1.8V supply and delivering the premium
audio quality our customers have come to expect," said Jason Rhode,
vice president and general manager, Mixed-Signal Audio Products
Division, Cirrus Logic. "The CS42L51 will finally enable designers
to stop sacrificing audio quality in their portable products due to
size and power constraints." In addition to a high-quality
multi-bit Delta Sigma based ADC and DAC, the CS42L51 integrates a
3:1 stereo input multiplexer, programmable gain amplifier, a stereo
microphone preamplifier and low-noise bias supply, automatic level
control, and a digital signal processing engine, which offers
features such as bass/treble boost, limiter and a tone generator.
Its analog stereo outputs can be configured as HP or line out, with
digital volume and mute output control. Pricing and Availability
The CS42L51 is currently sampling to customers, with volume
production expected in late summer 2005. The codec is available in
a 32-lead QFN package and is priced at $3.95 in quantities of
1,000. Cirrus Logic Inc. Cirrus Logic develops high-precision
