GENERAL DESCRIPTION
TZA3005H
The TZA3005H SDH/SONET transceiver chip is a fully
integrated serialization/deserialization STM1/OC3
(155.52 Mbits/s) and STM4/OC12 (622.08 Mbits/s)
interface device. It performs all necessary serial-to-parallel
and parallel-to-serial functions in accordance with
SDH/SONET transmission standards. It is suitable for
SONET-based applications and can be used in
conjunction with the data and clock recovery unit
(TZA3004), optical front-end (TZA3023 with TZA3034/44)
and a laser driver (TZA3001). A typical network application
is shown in Fig.10.
A high-frequency phase-locked loop is used for on-chip
clock synthesis, which allows a slower external transmit
reference clock to be used. A reference clock of 19.44,
38.88, 51.84 or 77.76 MHz can be used to support existing
system clocking schemes. The TZA3005H also performs
SDH/SONET frame detection.
The low jitter PECL interface ensures that Bellcore, ANSI,
and ITU-T bit-error rate requirements are satisfied.
The TZA3005H is supplied in a compact QFP64 package.
