• Manufacturer Part Number: m34116
• Description: Pcm Conference Call And Tone Generation Circuit
• Manufacturer: STMicroelectronics

ELECTRICAL CHARACTERISTICS (Tamb = 0 to 70 C, V
All DC characteristic are valid 250 s after V
load and R
Notes:
1. With Extra Bit operating mode insert this time becomes 3 t
2. With Extra Bit operating mode insert these times are 80ns longer.
3. With OPCODE (C/D = I), this time becomes 4tck (6tck if E = 1). E: extra bit indication in ”operating mode” instruction.
4. For tone generation instruction, this time becomes 4tck (6tck if E = 1) E: extra bit indication in ”operating mode” instruction.
5. With extra bit operating mode insert, this time becomes 6tck.
6. The initialization routine takes 2 frames time starting from the rising edge of RESET - Any access to the device should take place after the
