TDA5252G2 INFINEON [Infineon Technologies AG], TDA5252G2 Datasheet - Page 33

• Manufacturer Part Number: TDA5252G2
• Description: ASK/FSK 915MHz Wireless Transceiver
• Manufacturer: INFINEON [Infineon Technologies AG]

With default settings the clock generating units are disabled during PD, therefore no clock is
available at the clock output pin. It is possible to offer a clock signal at the clock output pin every
time (also during PD) if the CLK_EN Bit in the CONFIG register is set to HIGH.
