General Description

The VSC8113 is an ATM/SONET/SDH compatible transceiver integrating an on-chip Clock Multiplication

Unit (PLL) for the high speed clock as well as a clock and data recovery unit (CRU) with 8 bit serial-to-parallel

and parallel-to-serial data conversion. The PLL clock is used for serialization in the transmit direction (Mux).

The recovered clock is used for deserialization in the receive direction (Demux). The demultiplexer contains

SONET/SDH frame detection and recovery. The device provides both facility and equipment loopback modes

and two loop timing modes. The part is packaged in a 100PQFP with integrated heat spreader for optimum ther-

mal performance and reduced cost. The VSC8113 provides an integrated solution for ATM physical layers and

SONET/SDH systems applications.

Functional Description

The VSC8113 is designed to provide a SONET/SDH compliant interface between the high speed optical

networks and the lower speed User Network Interface devices such as the PM5355 S/UNI-622. The VSC8113

converts 8 bit parallel data at 77.76Mb/s or 19Mb/s to a serial bit stream at 622.08Mb/s or 155.52Mb/s respec-

tively. The device also provides a Facility Loopback function which loops the received high speed data and

clock (optionally recovered on-chip) directly to the high speed transmit outputs. A Clock Multiplier Unit

(CMU) is integrated into the transmit circuit to generate the high speed clock for the serial output data stream

from input reference frequencies of 19.44, 38.88, 51.84 or 77.76 MHz. The CMU can be bypassed with the

received/recovered clock in loop timing mode thus synchronizing the entire part to a single clock. The block

diagram on page 2 shows the major functional blocks associated with the VSC8113.

The receive section provides the serial-to-parallel conversion, converting the 155.52Mb/s or 622Mb/s bit

stream to an 8 bit parallel output at 19.44Mb/s or 77.76MHz respectively. A Clock Recovery Unit (CRU) is inte-

grated into the receive circuit to recover the high speed clock from the received serial data stream. The receive

section provides an Equipment Loopback function which will loop the low speed transmit data and clock back

through the receive section to the 8 bit parallel data bus and clock outputs.The VSC8113 also provides the

option of selecting between either its internal CRU’s recovered clock and data signals or optics containing a
