TDK Semiconductor has expanded its DS3/E3/STS1 LIU product family with multichannel LIUs. The three new devices operate with data rates of 34 Mbps (DS3), 45 Mbps (E3) and 51 Mbps (STS1). The primary product applications for the multiports include DSLAMs, T3/E3 digital multiplexers, SONET add/drop multiplexers, PDH equipment, DS3 to fibre-optic and microwave modems, and ATM WAN access for routers and switches.
The 78P7202L (dual port), 78P7203L (triple port) and 78P7204L (quad port), are extensions of the 78P7200L single chip IC. Each of the multiports is a line interface transceiver for E3, DS3 and STS-1 applications and offers a typical per port power dissipation of less than 300 mW at 3,3 V. Each channel can be individually powered down to reduce power in a redundant application. The devices include analog local loop-back and digital local loop-back as well as a clock polarity selection.
A new feature to the multiports is the input receiver MUX, which saves board space and component cost by replacing external switches. For example, when using the 78P7204L, transmitter one is able to monitor transmitter two and the same for transmitters three and four. This will allow the system to monitor whether there is an error detected on the active channel, and if so, automatically change to the redundant channel, so the 78P7202L can behave as a single channel device with a built in redundant channel.
Each channel features clock recovery and transmitter pulse shaping functions for applications using 75 Ohm coaxial cable at distances up to 335 m, compensating for 12 dB of cable and 6 dB of flat loss. In DS3 mode a line build out (LBO) function can be used to adjust the signal amplitude and pulse shape for cable lengths of 69 m or greater. Each device meets all ANSI and ITU specifications for jitter tolerance, jitter transfer and loss of signal as required by each data rate.
The 78P7202L comes in 80-lead TQFP package and the 7203L and 7204L in 128-lead TQFP packages.
