Description

Features

Functional Specification

- Suitable for SONET, SDH, Synchronous Ethernet appli-

cations

The RoHS 6/6 compliant STC5415 is a single chip

clock synchronization solution for line card applica-

tions in SDH, SONET, and Synchronous Ethernet

network elements.

- Supports 4 different frequencies of external oscillator

upon soft-reset: 10MHz, 12.8MHz, 19.2MHz, 20MHz

- Provides one 2kHz or 8kHz external frame sync input

- Accepts 5 clock reference inputs

The STC5415 accepts 5 clock reference inputs, 1

external frame sync input EX_SYNC, and generates

4 synchronized clock outputs. Synchronized outputs

may be programmed for wide variety of frequencies

from 1MHz up to 156.25MHz, in 1kHz steps. Refer-

ence inputs are individually monitored for activity and

quality. Reference selection may be automatic, man-

ual, or hard-wired manual.

- Supports automatically frequency detection or manually

acceptable frequency. Each reference input is monitored

for activity and quality

- Automatic, manual, and hard-wired manual reference

selection

- Outputs 4 synchronized clock outputs, including 2 frame

pulse clocks

- Frequency translation of input clock to a different local

line card clock

The timing generator may operate in the Freerun,

Synchronized, and Holdover mode. It includes a

DSP-based PLL. Synchronized mode is external tim-

ing while freerun and holdover mode are self-timing.

DSP-based PLL technology removes any external

component except the oscillator. It provides excellent

performance and reliability to STC5415.

- 3 clock synthesizers generate frequencies

- Phase-align locking or hit-less reference switching

- Programmable loop bandwidth, from 13Hz to 100Hz

- Programmable phase skew in synthesizer level

- SPI bus interface

The STC5415 is clocked by an external oscillator,

either a stable TCXO or XO, as required by applica-

tion.

- Single 3.3V operation

- Available in TQFP64 package
