Overview

Digital TV is an emerging trend. Digital TV signals need to be decoded by STB before they can be fully displayed. As analog circuit properties in an STB system may deviate from expected values due to process shifts, the deviation can be recorded in NVM for use in trimming. In addition, to ensure data security and privacy, NVM can be used for encryption key storage. eMemory provides complete solutions for these applications.

NeoBit STB Controller

The NeoBit OTP HR and NeoBit PMTP HR series can be utilized to store circuit parameter values and encryption keys in STB systems. The circuit parameters include Amp, DAC, Regulator, and PLL can be stored in NeoBit OTP HR. NeoBit OPT HR and NeoBit PMTP HR offer highly flexible encryption key management by allowing encryption keys to be stored during IC production or at the system integration stage for HDMI and copy-protection applications. In addition, these IPs allow users to adjust parameters at the CP or FT stage without the extra cost of additional masks.
