General Description

The VSC8114 is an ATM/SONET/SDH compatible transceiver integrating an on-chip Clock Multiplication

Unit (PLL) for high speed clock generation 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 direc-

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

contains SONET/SDH frame detection and recovery. In addition, the device provides both facility and equip-

ment loopback modes and a loop time mode. The part is packaged in a 100PQFP with an integrated heat

spreader for optimum thermal performance and reduced cost. The VSC8114 provides an integrated solution for

ATM physical layers and SONET/SDH systems applications.

Functional Description

The VSC8114 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 VSC8114

converts 8 bit parallel data at 77.76Mb/s to a serial bit stream at 622.08Mb/s. 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 gen-

erate the high speed clock for the serial output data stream from input reference frequencies of 19.44 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 VSC8114.

The receive section provides the serial-to-parallel conversion, converting 622Mb/s bit stream to an 8 bit par-

allel output at 77.76MHz. A Clock Recovery Unit (CRU) is integrated 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 out-

puts. The VSC8114 also provides the option of selecting between either its internal CRU’s clock and data sig-

nals, or optics containing a CRU clock and data signals. The receive section also contains a SONET/SDH frame
