DS2153Q
4 of 60
1 DETAILED DESCRIPTION
The DS2153Q E1 single-chip transceiver (SCT) contains all the necessary functions for connection to E1
lines. The on-board clock/data recovery circuitry coverts the AMI/HDB3 E1 waveforms to a NRZ serial
stream. The DS2153Q automatically adjusts to E1 22 AWG (0.6mm) twisted-pair cables from 0 to 1.5km.
The device can generate the necessary G.703 waveshapes for both 75
and 120 cables. The on-board
jitter attenuator (selectable to either 32 bits or 128 bits) can be placed in either the transmit or receive data
paths. The framer locates the frame and multiframe boundaries and monitors the data stream for alarms. It
is also used for extracting and inserting signaling data, Si, and Sa-bit information. The device contains a
set of 71 8-bit internal registers that the user can access to control the operation of the unit. Quick access
via the parallel control port allows a single micro to handle many E1 lines. The device fully meets all the
latest E1 specifications, including ITU G.703, G.704, G.706, G.823, and I.431 as well as ETSI 300 011,
300 233, TBR 12 and TBR 13.
1.1 Introduction
The analog AMI waveform off of the E1 line is transformer coupled into the RRING and RTIP pins of
the DS2153Q. The device recovers clock and data from the analog signal and passes it through the jitter
attenuation mux to the receive side framer where the digital serial stream is analyzed to locate the framing
pattern. If needed, the receive side elastic store can be enabled in order to absorb the phase and frequency
differences between the recovered E1 data stream and an asynchronous backplane clock which is
provided at the SYSCLK input.
The transmit side of the DS2153Q is totally independent from the receive side in both the clock
requirements and characteristics. The transmit formatter will provide the necessary data overhead for E1
transmission. Once the data stream has been prepared for transmission, it is sent via the jitter attenuation
mux to the waveshaping and line driver functions. The DS2153Q will drive the E1 line from the TTIP
and TRING pins via a coupling transformer.
1.2 Reader’s Note
This data sheet assumes a particular nomenclature of the E1 operating environment. There are 32 8-bit
time slots in E1 systems that are numbered 0 to 31. Time slot 0 is transmitted first and received first.
These 32 time slots are also referred to as channels with a numbering scheme of 1 to 32. Time slot 0 is
identical to channel 1, time slot 1 is identical to channel 2, and so on. Each time slot (or channel) is made
up of 8 bits numbered 1 to 8. Bit number 1 is the MSB and is transmitted first. Bit number 8 is the LSB
and is transmitted last. Throughout this data sheet, the following abbreviations are used:
FAS
Frame Alignment Signal
CAS
Channel Associated Signaling
MF
Multiframe
Si
International Bits
CRC4
Cyclical Redundancy Check
CCS
Common Channel Signaling
Sa
Additional bits
E-bit
CRC4 Error bits
