' OCP DTR-xxx-LC & DTR-xxx-LS 3.3 Volt 2x5 LC connector OC-3 & OC-12 LED Transceivers Features Designed for ATM/SONET/SDH OC-3 (156 Mb/s) & OC-12 (622 Mb/s) Multi-sourced 10-pin (2x5) SFF (Small Form Factor) package style Duplex LC optical connector interface Excellent EMI & ESD protection - 40C to +85C Operating Temperature ("A" option) Single +3.3 V supply & LV-PECL DATA interface Option for LV-TTL or LV-PECL SIGNAL DETECT output Description The transmitter incorporates a highly reliable 1300 nm InGaAsP surface-emitting LED and a driver circuit which converts LV-PECL data to light. A LV-TTL Transmitter Disable control input is also provided. The receiver features a transimpedance amplifier IC for high sensitivity and wide dynamic range. The Receiver Signal Detect status output can be either LV-TTL or LV-PECL. The DTR-xxx-LC and DTR-xxx-LS fiber optic transceivers offer a simple, convenient way to interface PCBs to multimode fiber optic cables. They are designed for ATM/SONET/SDH applications at OC-3/STM-1 (156 Mb/s) and OC-12/STM-4 (622 Mb/s). The transmit and receive functions are contained in a narrow width two-row, 10-pin (2x5) package with a Duplex LC connector interface. The receptacle fits into an RJ-45 form factor outline. The 10-pin configuration is in conformance to a Small Form Factor (SFF) multisource transceiver agreement. The transceiver operates from a single +3.3V power supply over an operating temperature range of 0C to +70C or - 40C to +85C ("A" option). The package is made of either conductive plastic or metal for excellent EMI shielding Absolute Maximum Ratings Parameter Symbol Minimum Maximum Units Tst - 40 + 85 C - 40 + 85 0 + 70 Storage Temperature Operating Temperature "A" option Top "blank" option C Supply Voltage VCC 0 + 6.0 V Input Voltage Vin 0 VCC V Output Current IO - 50 Lead Soldering Temperature & Time - - mA 260 C, 10 sec Optical Communication Products, Inc. 1 21737-0252, Rev.

Application Notes Pin Assignments Transmitter: When the DATA+ input is at logic HIGH and DATA- input is at logic LOW, the LED is ON; and vice versa. The transmitter is normally enabled (i.e. when the TX DISABLE control input is not connected). When the TX DISABLE control input voltage is higher than VCC - 1.3 V, the LED is turned off independent of the input data. PIN Receiver: Both differential DATA+ and DATA- outputs are LV-PECL levels requiring proper termination (see recommended interface circuits). For optimum performance, both outputs should be terminated in the same manner, even if only one is used. The Signal Detect circuit monitors the level of the incoming optical signal and generates a logic LOW signal when insufficient photocurrent is produced. If the SIGNAL DETECT output is LV-TTL level, no termination is required. If the SIGNAL DETECT output is LV-PECL level, a termination resistor of 160 ohms to GND is required. 21737-0252, Rev.
