DTC-03

OC-3/STM-1 Single Mode Transceiver

with Clock Recovery

The DTC-03 fiber optic transceivers with clock recovery offer a

simple, convenient way to interface SONET/SDH OC-3/STM-1

PCBs to single mode fiber optic cables. Both Long Reach (1300 nm

or 1550 nm) and Intermediate Reach versions are available. All

modules satisfy Class I Laser Safety requirements in accordance with

the US FDA/CDRH and international IEC-825 standards.

The transmit and receive functions are contained in a two-row, 18-pin

(2x9) package with a Duplex SC or ST or FC connector interface.

The transmitter incorporates a highly reliable 1300 nm or 1550 nm

InGaAsP Laser and a driver circuit which converts PECL data to

light. The receiver incorporates efficient 1300 nm InGaAs/InP PIN

photodiodes converting the light signal into an electrical current which

is amplified and resampled using internal clock recovery (PLL) to

generate PECL-compatible data and clock. The transimpedance

amplifier IC has an internal AGC for wide dynamic range.

The transceiver operates from a single +5V supply over an operating

temperature range of 0°C to +70°C (B option) or - 40°C to +85°C

(A option). The package is made of either conductive plastic with

blue color (Duplex-SC version) or metal (FC and ST version) for

excellent EMI shielding.

Transmitter: When the DATA+ input is at logic HIGH and DATA-

input is at logic LOW, the LD is ON; and vice versa. In single-ended

applications, the unused input pin should be biased to VCC - 1.29 V.

The transmitter is normally enabled (i.e. when the TX DISABLE input

is not connected). When the TX DISABLE input voltage is higher than

VCC - 2 V, the laser is turned off independent of the input data. A

Transmitter End-of-Life Alarm (TALM) is also provided, which will switch

to TTL level HIGH when the laser is reaching its End-of-Life.

The transmitter incorporates an Average Power Control (APC) loop

to stabilize the transmitter average optical output power against

temperature variation. The APC loop always acts to keep the

transmitter average optical output power at a constant value (assuming

that the transmitter is enabled). Therefore, when the input data is all

continuous zeroes or all continuous ones, the transmitter optical

output power is a constant level equal to the nominal average optical

output power (not at the OFF level or at the ON level).

Receiver: Both differential outputs (DATA+ and DATA-, CLOCK+

and CLOCK-) are PECL levels requiring termination (50 ohms to

VCC - 2 volts or 510 ohms to GND is recommended). 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 TTL logic LOW signal

when insufficient photocurrent is produced. Control

Interface circuit: The power supply line should be well-filtered.

All 0.1 mF power supply bypass capacitors should be as close to

the DTC transceiver module as possible. The two front GND posts

should be grounded to Circuit Ground or Chassis Ground.

Laser Safety: All transmitters are Class I Laser products per FDA/

CDRH and IEC-825 standards. They must be operated under

specified operating conditions.
