4 / 37 page  XRT5997 4 Rev. 1.0.0 Pin# Symbol Type Description 1 RxPOS1 O Receiver 1 Positive Data Out: This output pin will pulse “high” whenever Channel 1, within the XRT5997 device has received a “Positive Polarity” pulse, in the incoming line signal, at RTIP1/RRing1 inputs. 2 RxNEG1 O Receiver 1 Negative Data Out: This output pin will pulse “high” whenever Channel 1, within the XRT5997 device has received a “Negative Polarity” pulse, in the incoming line signal, at tRTIP1/RRing1 inputs. 3 DVDD - Positive Supply - (+3.3V ± 5%). Digital Circuitry. 4 LOS7 O Receiver 7 Loss of Signal Output Indicator: This output pin toggles “high” if Channel 7, within the XRT5997 device has detected a “Loss of Signal” condition in the incoming line signal. 5 RxPOS7 O Receiver 7 Positive Data Out: This output pin will pulse “high” whenever Channel 7, within the XRT5997 device has received a “Positive Polarity” pulse, in the incoming line signal, at RTIP7/RRing7 inputs. 6 RxNEG7 O Receiver 7 Negative Data Out: This output pin will pulse “high” whenever Channel 7, within the XRT5997 device has received a “Negative Polarity” pulse, in the incoming line signal, at RTIP7/RRing7 inputs. 7 RTIP1 I Receiver 1 Positive Bipolar Input: The Receive Section of Channel 1 uses this input pin, along with RRing1 to receive the bipolar line signal from the “Remote E1 Terminal”. 8 RRing1 I Receiver 1 Negative Bipolar Input: The Receive Section of Channel 1 uses this input pin, along with RTIP1 to receive the bipolar line signal from the “Remote E1 Terminal”. 9 AVDD - Positive Supply - (+3.3V ± 5%). Analog Circuitry. 10 AGND - Analog Ground 11 AVDD Positive Supply - (+3.3V ± 5%). Receiver 1, 2, 3, 5. 12 RRing2 I Receiver 2 Negative Bipolar Input: The Receive Section of Channel 2 uses this input pin, along with RTIP2 to receive the bipolar line signal from the “Remote E1 Terminal”. 13 RTIP2 I Receiver 2 Positive Bipolar Input: The Receive Section of Channel 2 uses this input pin, along with RRing2 to receive the bipolar line signal from the “Remote E1 Terminal”.
