Overview
Intel® LXT384 Octal T1/E1/J1 Short-Haul PCM Transceiver with Jitter Attenuation (JA) Datasheet Product Features ■ ■ ■ ■ ■ ■ ■ Octal T1/E1/J1 Pulse-Code Modulation (PCM) Transceiver with Jitter Attenuation for use in both 1.
544 Mbps (T1) and 2.
048 Mbps (E1) applications 16 fully-independent receiver/transmitters Support for E1 standards: — Exceeds ETSI ETS 300 166 — Meets ETS 300 233 Low-power single-rail 3.
3-V CMOS power supply, with 5-V tolerant I/Os Jitter attenuation — Crystal-less — Digital clock recovery PLL — Referenced to a low frequency 1.
544 MHz or 2.
048-MHz clock.
Normal operation requires only MCLK.
Does not require a reference clock frequency higher than the line frequency.
— Can be switched between receive and transmit path — Meets ETSI CTR12/13, ITU G.
736, G.
742, G.
823, and AT&T Pub 62411 — Optimized for Synchronous Optical NETwork (SONET) and Synchronous Digital Hierarchy (SDH) applications, meets ITU G.
783 mapping jitter standard — Constant throughput delay Differential receiver architecture — High margin for noise interference — Operates at >12 dB of cable attenuation Intel® Hitless Protection Switching — Eliminates mechanical relays for redundancy 1+1 protection applications — Increases quality of service ■ ■ ■ ■ ■ ■ ■ ■ Transmitters — Power-down mode with fast output tristate capability — Transmit waveform shaping meets ITU G.
703 and T1.
102 specifications — Exceeds ETSI ETS 300 166 transmit return-loss specifications — Low-impedance transmit drivers, independent of transmit pattern and supply-voltage variations — Low-current transmit output option that can reduce power dissipation by up to 15%.
By changing the LXT384 Transceiver output transformer ratio from 1:2 to 1:1.
7, the savings occur whether TVCC is at 5 V or 3.
3 V.
130 mW per channel (typical).
