DS26519 Datasheet | Maxim Integrated

DESCRIPTION The DS26519 is a single-chip 16-port framer and line interface unit (LIU) bination for T1, E1, and J1 applications. Each port is independently configurable, supporting both long-haul and short-haul lines. The DS26519 is nearly software patible with the DS26528 and its derivatives. FEATURES 16 plete T1, E1, or J1 Long-Haul/ Short-Haul Transceivers (LIU Plus Framer) Independent T1, E1, or J1 Selections for Each Transceiver Software-Selectable Transmit- and Receive Side Termination for 100Ω T1 Twisted Pair, 110Ω J1 Twisted Pair, 120Ω E1 Twisted Pair, and 75Ω E1 Coaxial Applications Hitless Protection Switching Crystal-Less Jitter Attenuators Can Be Selected for Transmit or Receive Path; Jitter Attenuator Meets ETS CTR 12/13, ITU-T G.736, G.742, G.823, and AT&T Pub 62411 External Master Clock Can Be Multiple of 2.048MHz or 1.544MHz for T1/J1 or E1 Operation; This Clock is Internally Adapted for T1 or E1 Usage in the Host Mode Receive-Signal Level Indication from -2.5d B to -36d B in T1 Mode and -2.5d B to -44d B in E1 Mode in Approximate 2.5d B Increments APPLICATIONS Routers Channel Service Units (CSUs) Data Service Units (DSUs) Muxes Switches Channel Banks T1/E1 Test Equipment FUNCTIONAL DIAGRAM T1/E1/J1 NETWORK ..
