... General Description The MICRF610 is a self-contained frequency shift keying (FSK) transceiver module, intended for use in half-duplex, bidirectional RF links. The transceiver module is intended for UHF radio equipment in compliance with European Telecommunication Standard Institute (ETSI) specification EN300 220. The transmitter consists of a fully programmable PLL frequency synthesizer and power amplifier ...

... Micrel, Inc. Power on Reset When applying voltage to the MICRF610 a power on reset state is entered. During the time period of power on reset, the MICRF610 should be considered unknown state and the user should wait until completed (See Table 6). The power on reset timing given in table 6 is covering all conditions and should be treated as a maximum delay time ...
