zl50235 Zarlink Semiconductor, zl50235 Datasheet - Page 30

• Manufacturer Part Number: zl50235
• Description: 16 Channel Voice Echo Canceller
• Manufacturer: Zarlink Semiconductor

These peak detector registers allow the user to monitor the send in (Sin) peak signal level. The information is in
16 bit 2’s complement linear coded format presented in two 8 bit registers for each echo canceller. The high
byte is in Register 2 and the low byte is in Register 1.
