TDA5250D2_07 INFINEON [Infineon Technologies AG], TDA5250D2_07 Datasheet - Page 37

• Manufacturer Part Number: TDA5250D2_07
• Description: ASK/FSK 868MHz Wireless Transceiver
• Manufacturer: INFINEON [Infineon Technologies AG]

Table 2-32
Note: Data are valid 500 µs after the crystal oscillator is enabled (see Figure 2-15 and Figure 2-
16, t CLKSU ).
Table 2-33
Note: As long as default settings are used, there is no clock available at the clock output during
Power Down. It is possible to enable the clock during Power Down by setting CLK_EN (Bit D9) in
the Config Register (00H) to HIGH.
2.4.20
The input of the 6Bit-ADC can be switched between two different sources: the RSSI voltage (default
setting) or a resistor network dividing the Vcc voltage by 5.
