2.2.1 Internal Power Supply
The internal stages of the TLI5012B E1000 are supplied with several voltage regulators:
⢠GMR Voltage Regulator, VRG
⢠Analog Voltage Regulator, VRA
⢠Digital Voltage Regulator, VRD (derived from VRA)
These regulators are directly connected to the supply voltage VDD.
2.2.2 Oscillator and PLL
The digital clock of the TLI5012B E1000 is given by the Phase-Locked Loop (PLL), which is by default fed by an
internal oscillator. In order to synchronize the TLI5012B E1000 with other ICs in a system, the TLI5012B E1000
