AEAT-9922中文资料10- to 18-Bit Programmable Angular Magnetic Encoder数据手册Broadcom规格书

描述 Description

The Broadcom AEAT-9922 is an angular magnetic rotary sensor that provides accurate angular measurement over a full 360 degrees of rotation. It is a sophisticated system that uses integrated Hall sensor elements with complex analog and digital signal processing within a single device.A simple two-pole magnet generates the necessary magnetic field by rotating it in perpendicular. Wide magnetic field sensor configurations allow On Axis (end of shaft) or Off Axis (side of shaft) modes in application.The Broadcom AEAT-9922 is a versatile solution capable of supporting a broad range of applications with its robust architecture to measure and deliver both absolute and incremental signals.The absolute angle measurement provides an instant indication of the magnet's angular position with a selectable and one-time programmable resolution from 10 to 18 bits.When selected, its positioning data is then represented in its digital form to be assessed through a standard SSI (parity) and SPI (with CRC and Parity option) communication protocol.Where desired, users may also choose to receive its absolute angle position in PWM-encoded output signals (with CRC). The incremental positions are output as ABI and UVW signals. Wide user configurable resolutions are available from 1CPR and up to 10,000CPR.of ABI signals and pole pairs from 1 to 32pole pairs (2 to 64 poles) for UVW commutation signals.For easy evaluation of the encoder IC, the HEDS-9922PRGEVB evaluation kit set (inclusive of the SPI programming kit, the pre-assembled AEAT-9922 evaluation boards and the on-axis magnets) is available for orders through normal Broadcom Sales Channels.  Ordering Part NumbersAEAT-9922-100    18 Bits Magnetic Encoder On-Off Axis,QFN 24 leads, 4 mm × 4 mm, Tape & Reel: 1000 pieces per reel.AEAT-9922-102    18 Bits Magnetic Encoder On-Off Axis,QFN 24 leads, 4 mm × 4 mm, Tape & Reel: 100 pieces per reel.AEAT-9922-Q24    18 Bits Magnetic Encoder On-Off Axis,QFN 24 leads, 4 mm × 4 mm, Tube: 73pcs per tube.HEDS-9922PRGEVB    AEAT-9922 Programming Kit & Evaluation SetHEDS-9922EVB    AEAT-9922 Evaluation Board
