MC145484SDR2 - Brand New MOTOROLA Interface - CODECs
-
Description
Electronic Component Model: MC145484SDR2
Product Category: Interface - CODECs
The MC145484 is a general purpose per channel PCM Codec–Filter with pin selectable Mu–Law or A–Law companding. It is offered in 20–pin SOG and SSOP packages. This device performs the voice digitization and reconstruction as well as the band limiting and smoothing required for PCM systems. The MC145484 PCM Codec–Filter utilizes CMOS due to its reliable low–power performance and proven capability for complex analog/digital VLSI functions.
Key Features:
• Single 5 V Power Supply
• Typical Power Dissipation of 15 mW, Power–Down of 0.01 mW
• Fully–Differential Analog Circuit Design for Lowest Noise
• Transmit Band–Pass and Receive Low–Pass Filters On–Chip
• Active R–C Pre–Filtering and Post–Filtering
• Mu–Law and A–Law Companding by Pin Selection
• On–Chip Precision Reference Voltage of 1.575 V for a – 0 dBm TLP @ 600 Ω
• Push–Pull 300 Ω Power Drivers with External Gain Adjust
• MC14LC5480EVK is the Evaluation Kit for This Device
