Broadcom AEDR-9930E 3-Ch Reflective Optical Encoder


Broadcom AEDR-9930E 3-Channel Reflective Optical Encoder offers selectable and programmable options of digitally differential A, B, and I outputs. The AEDR-9930E digital encoder mode provides two-channel (AB) quadrature digital outputs and a third-channel digital index output.

The Broadcom AEDR-9930E encoder is TTL compatible with interfaced outputs for most signal processing circuitries. Therefore, the AEDR-9930E enables easy integration and flexible design-in into existing systems.

The device is developed to operate over a -40°C to +115°C temperature range and is ideal for commercial, industrial, and automotive end applications. The encoder encloses an LED light source and photo-detecting circuitry in a 5.00mm × 5.00mm  × 1.05mm (LxWxH) single package. The small size of the AEDR-9930E permits usage in a wide range of miniature commercial applications, where size and space are primary concerns.


  • Digital output option: three-channel differential or TTL compatible; two-channel quadrature (AB) digital outputs for direction sensing and a third channel, index digital output
  • Wide-selection built-in interpolator with 1x to 10x, 12x, 14x, 15x, 16x, 18x, 20x, 25x, 32x, 50x, 64x, 80x, 100x, 128x, 160x, 256x to 512x and other user-programmable interpolation factors
  • SPI programmable interpolator from 1x to 1024x
  • 5.0mm × 5.0mm × 1.05mm (LxWxH) surface-mount leadless package
  • Operating voltage of 3.3V and 5.0V supply
  • Built-in LED current regulation
  • Wide operating temperature range from -40°C to +115°C
  • High encoding resolution of 397LPI (lines per in.) or 15.63LPmm (lines per mm)
