Notes:
- 4 layer PCB: 2 layers for Customer Reference and 2 layers for Evaluation.
- 20 mil trace (minimum) on all power and ground routes.
- Decoupling capacitors are physically close to U1 VDD and U2 VCC, respectively.
- Designed for TMD2772, and can be used with TMD3782
and
other mechanically compatible 8-pin Type-A module packaged devices.
- All resistors are EIA 0603 and capacitors are EIA 0402, unless otherwise noted.
- Assembly drawing: TE-00-00108
