Product specication
DTMF/modem/musical-tone generators
PCD3311C; PCD3312C
Notes
1. Oscillator ON; VDD = 3 V; crystal connected between OSCI and OSCO; D0/SCL and D1/SDA connected via
resistance of 5.6 k
to VDD; all other pins left open.
2. As note 1, but with oscillator OFF.
3. Related to the level of the LOW group frequency component, according to CEPT recommendations.
4. Related to the level of the fundamental frequency.
5. Oscillator must be running.
6. Values are referenced to the 10% and 90% levels of the relevant pulse amplitudes, with a total voltage swing from
VSS to VDD.
