Notes
1. External clock signal (frequency = 76.8 kHz, amplitude = V_SS to V_DD) at pin EXTAL; OSCPD = HIGH;
test inputs = LOW; other inputs = HIGH; outputs unconnected; SPI transmit enabled; COD bit set to logic 1 (see
Section 8.4.4); to obtain the supply current of an application with a crystal connected as in Fig.19, a typical oscillator
current of 2 µA needs to be added to this value (see Chapter 14); T_amb = 25 °C.
2. As note 1, but PCD5013 and synchronous to a typical FLEX™ data stream (collapse value = 4), T_amb = 25 °C.
13 AC CHARACTERISTICS
T_amb = −25 to +70 °C, V_DD = 1.8 to 3.6 V, f_EXTAL = 76.8 kHz, maximum load capacitance = 50 pF connected to any
digital output; unless otherwise specified.
