TSYN01622 SONET/SDH/PDH/AClock Synthesizer
Description
Agere Systems TSYN01622 designed wide variety synchronous timing applications. serves clock synthesizer skew clock fan-out device generating clocks frequencies 622.08 that synchronized system reference clock. TSYN01622 also delivers output sync signal that aligned input clock. system sync signals applied clock input, TSYN01622 will generate output sync signal that phase aligned selected input sync. programmable phase offset provided allow user offset output sync relative input sync. output sync used global alignment cells frames SONET/SDH/PDH cross connects Aswitch applications. device allows flexible choices LVDS LVCMOS input technologies LVDS, LVPECL, LVCMOS output technologies. TSYN01622 programmed external balls, through serial interface. Enhanced functionality available through serial interface, including programmable clock outputs through fractional synthesis, ability enable disable each output individually.
Fully integrated clock synthesis Supports wide choice SONET/SDH output clock frequencies: 622.08 51.84 34.368 19.44 4.096 1.544 155.52 44.736 32.768 16.384 2.43 77.76 38.88 24.704 8.192 2.048
Five frequency programmable clock outputs Supports multiple input clock frequencies: 51.84 8.192 1.544 38.88 6.48 19.44 2.048
Generates sync outputs aligned input clock signal skew clock distribution balls Compatible with Agere Systems TTRN012G5 Gbits/s MUX/Synthesizer, TDAT042G5/ TADM042G5 SONET/ATM/POS devices, TSOT0410G, STSI-144, TSI-16, TSI-8, TMXF84622 Ultramapper, TMXF28155 Supermapper Single supply Multiple output technologies-CMOS, LVPECL, LVDS Programmable external balls internal registers serial interface
Applications

TSYN01622 SONET/SDH/PDH/AClock Synthesizer
Functional Overview
TSYN01622 designed manage clock generation timing distribution SONET/SDH compliant line card solutions OC-48 data rates. Additional external circuitry used extend TSYN01622 performance OC-192 transmitter applications. TSYN01622's output clocks designed meet relevant output clock jitter generation specifications maximum time interval error (MTIE). supports range common input frequencies from 51.84 MHz. integrated digital state machine monitors presence input clock signal. Programming TSYN01622 accomplished through external ball control through internal registers serial interface. range SONET clock frequencies generated with clocks available multiple low-skew LVDS LVPECL output buffers order provide fan-out clock distribution sources multiple chips within system. sync signal with user-programmable offset generated available CMOS, LVDS, LVPECL output buffers. duty cycle output sync signal selectable either width single clock pulse determined maximum selected SONET/SDH related output frequency.
