OCTAL E1 SHORT HAUL
LINE INTERFACE UNIT
IDT82V2058
FEATURES
♦ Fully integrated octal E1 short haul line interface which
supports 120Ω E1 twisted pair and 75Ω E1 coaxial appli-
cations
♦ Selectable single rail or dual rail mode and AMI or HDB3
line encoder/decoder
♦ Built-in transmit pre-equalization meets G.703
♦ Selectable transmit/receive jitter attenuator meets ETSI
CTR12/13, ITU G.736, G.742 and G.823 specifications
♦ SONET/SDH optimized jitter attenuator meets ITU G.783
mapping jitter specification
♦ Digital/analog LOS detector meets ITU G.775 and ETS 300
233
♦ ITU G.772 non-intrusive monitoring for in-service testing
for any one of channel1 to channel7
♦ Low impedance transmit drivers with tri-state
♦ Selectable hardware and parallel/serial host interface
♦ Local and remote loopback test functions
♦ Hitless Protection Switching (HPS) for 1 to 1 protection
without relays
♦ JTAG boundary scan for board test
♦ 3.3V supply with 5V tolerant I/O
♦ Low power consumption
♦ Operating temperature range: -40°C to +85°C
♦ Available in 144-pin Thin Quad Flat Pack (TQFP_144_DA)
