![]() ![]() Included with the player was MediaSource, the music management software that would be used with subsequent Zen players. The Zen NX, as it was later called, was released on August 20, 2003, is an upgrade to the old NOMAD Jukebox Zen, with a removable battery and a slightly smaller size. Up to 14 hours of continuous audio playback is achieved by the rechargeable battery, and an optional wired remote gives the player an FM tuner and microphone. It had the distinct ability to connect via USB 1.1 or FireWire, while subsequent releases had connectivity to USB 2.0. Unlike the earlier NOMAD Jukebox players, which looked like CD players, these have the appearance of a cassette player.Īnnounced on October 14, 2002, the NOMAD Jukebox Zen was the first player to include the "Zen" branding. The 2.5-inch Fujitsu hard drives range from a 20 (NOMAD Jukebox Zen), 30 (Zen NX, Zen Xtra), 40 and 60 GB (Xtra). The first models branded as a "Zen" were then released under the now-defunct NOMAD line, and have an anodized aluminium case. NOMAD Jukebox Zen players feature easily replaceable batteries They are natively compatible with Windows, with some also supporting Mac OS X. Some models are PlaysForSure-certified for being compatible with Windows Media Player via Media Transfer Protocol (MTP) and supporting the Janus DRM. They are bundled with device drivers and Creative MediaSource, a media player that includes transferring and syncing abilities exclusively for the players. The ZEN series had a strong foothold in Asian Pacific markets, especially in Singapore, the company's headquarters.Īll players support MP3 and WMA formats, while some models support also WAV and Audible formats. Three Creative Zens (the Portable Media Center, Micro Photo, and Vision:M) won the Best of CES award from 2004 to 2006 in their respective categories, with the latter winning the overall award. The last Creative Zen player, X-Fi3, was released at the end of 2011. The players evolved from the NOMAD brand through the NOMAD Jukebox series of music players, with the first separate "ZEN" branded models released in 2004. ZEN is a series of discontinued portable media players designed and manufactured by Creative Technology Limited. Creative ZENĬreative Technology (also known as Creative Labs in the west)ĭigital audio players, Portable media playersĢ5 million (as of 2007, includes NOMAD and MuVo) For the model in this series simply named "ZEN", see ZEN (portable media player). You can download this datasheet by clicking here.This article is about the portable media player series. It is recommended to go through the data sheet of PCM 2704CDB IC before going to build this circuit.Loudspeakers or Low impedance headphones must need an amplifier circuit at Vout terminals to make audio signals audible.+5V DC and +3.3V DC power supplies have to be derived from respective low dropout (LDO) regulators.Most feasible and low cost alternative to commercial MP3 players Note: Portable device as it consist less number of componentsįacilitates headphones as well as audio speaker output We can extend this circuit for remote control operation by adding an IR sensor with the corresponding receiver circuit. ![]() We can also connect audio speaker in place of headphones using appropriate power amplifier circuit between Vout pins and audio speaker. It is also possible to increase/decrease the volume and also mute by pressing corresponding push buttons connected to HID pins. This IC decodes the received data and converts to the analog audio which will be available at the VoutR and VoutL pins of the IC. Due to high speed transceivers, all this data transfer is carried out at full speed. Once the circuit is powered, it gets audio data and control data from USB through D- and D+ pins. Turn ON the power supply to the circuit by giving two respective DC voltages to the pins. ![]() Connect the power supply 5V (VBUS) to the respective pins shown in the figure.Connect a headphone to headphone jack by taking inputs from Vout R (15) and Vout L (14) of the IC.And also connect the 12 MHz crystal oscillator and all remaining capacitors to the pins as shown in the figure. Connect each push button to Human Interface Device (HID) pins (HID0, HID1 and HID2) through 1.5K ohm resistors by making a common connection to suspend flag pin.Connect the pins of USB female connector to the respective pins of PCM 2704CDB IC (D+, D- and VBUS) making sure that D+ and D- pins are connected through 22 ohm resistor.It is to be noted that it is a plug and play device which requires no software code. This IC can operate in an adaptive asynchronous mode for playback functions. This 28 pin IC is a stereo audio digital to analog converter with USB 2.0 interface compatible. This design uses PCM 2704CDB IC chip as a heart of this circuit. ![]()
