Notes

1. Inputs: SDA and SCL pulled up to VDD; all other inputs connected to VSS.

Outputs: RXE and ROE logic 0; REF: fref = 1⁄60 Hz; all other outputs open-circuit.

Oscillator: no crystal; external clock fosc = 76800 Hz; amplitude: VSS to VDD.

Voltage convertor disabled (SPF byte 01, bit D7 = 0; see Table 24).

2. Maximum output current is subject to absolute maximum ratings per output (see Chapter 10).

3. When ATL (open drain output) is not activated it is high impedance.

12 DC CHARACTERISTICS (WITH VOLTAGE CONVERTER)

VDD = 2.7 V; VSS =0V; VPR =VPO; Tamb = −25 to +70 °C; Cs = 100 nF; voltage converter enabled.

13 OSCILLATOR CHARACTERISTICS

Quartz crystal type: MX-1V or equivalent.

Quartz crystal parameters: f = 76 800 Hz; RS(max) =35kΩ; CL = 8 pF; C0 = 1.4 pF; C1 = 1.5 fF.

Maximum overall tolerance:

±200 × 10−6 (includes: cutting, temperature, aging) for POCSAG, ± 55 × 10−6 for APOC-1

(‘transmitter off’ mode).
