SA2531A規(guī)格書詳情

GENERAL DESCRIPTION

The SA2531 is a CMOS integrated circuit that contains all the functions needed to form a high performance electronic telephone.

The device incorporates LD/MF repertory dialling, melody generation, ring frequency discrimination and a high quality speech circuit.

A RAM is on chip for a 31 digit last number redial and 14 memories each containing up to 21 digits. The sliding cursor procedure makes Last Number Redial easy behind a PABX.

The SA2531 (exept the SA2531D) incorporates a volume control for the earpiece. The receive volume can be controlled by the VOL key (+4dB) or by the +/- keys (+6dB/-4dB in 5 steps).

The versatility of the circuit is provided by on chip programmability and a few external components. This allows easy adaption to different PTT requirements without changing the PCB of the telephone.
