IELK1-1REC4-52-60-0-K-01-V - Brand New Sensata / Airpax IC Chips
-
Description
The IELK1-1REC4-52-60-0-K-01-V is a second-generation Line Interface Unit (LIU) designed by Teridian Semiconductor Corp. It is specifically developed for telecom interfaces including 155 Mbps SDH/SONET (OC-3, STS-3, or STM-1) and 140 Mbps PDH (E4). This dual-channel, single-chip solution features an integrated CDR in the transmit path for flexible NRZ to CMI conversion. It can be used with both 75Ω coaxial cable using CMI coding and fiber optics transceiver module using NRZ coding. The IELK1-1REC4-52-60-0-K-01-V complies with all applicable ANSI, ITU T, and Telcordia standards for jitter tolerance, generation, and transfer.
Specifications and features
- ITU-T G.703 compliant cable driver for 139.264 Mbps or 155.52 Mbps CMI-coded coax transmission
- Integrated adaptive CMI equalizer and CDR in receive path handles over 12.7dB of cable loss
- Serial, LVPECL system interface with integrated CRU in transmit path for flexible NRZ to CMI conversion
- 4-bit parallel CMOS system interface with master and slave Tx clock modes
- Selectable LVPECL compatible NRZ media interface for 155.52 Mbps optical transmission
- Configurable via HW control pins or 4-wire serial port interface
- Compliant with ANSI T1.105.03-1994; ITU-T G.751, G.813, G.823, G.825, G.958; and Telcordia GR-253-CORE for jitter performance
- Receiver Loss of Signal (LOS) detection compatible with ITU-T G.783
- Operates from a single 3.3V supply
- Standard and thermally enhanced 128-pin JEDEC LQFP package options
Application Scenarios
The IELK1-1REC4-52-60-0-K-01-V is widely used in various telecommunication applications, particularly in SDH/SONET and PDH systems. It is suitable for transmitting high-speed data over coaxial cable or fiber optics with minimal signal loss. Its flexible interface options and compliance with industry standards make it a reliable choice for network infrastructure and communication equipment.
