- Digital Transmitter: A DFB laser diode is employed for upstream transmission at OC-24 (1244Mbps). The optical transmitter includes a back
facet photodetector to monitor laser power for APC control.
- Digital Receiver: An APD with TIA is employed for downstream data reception at OC-48 (2488Mbps). A post amplifier is also included for CML
output compatibility.
- Analog Receiver: 870MHz forward path video (CATV) receiver with multiple gain stages, automatic gain control (AGC), and status indicators.

Table 9 - Device Handling/ESD Protection
The devices are static sensitive and may easily be damaged if care is not taken during handling. The following handling practices
pract
are
recommended.
1
Devices should be handled on benches with conductive and grounding surfaces.
2
All personnel, test equipment and tools shall be grounded.
3
Do not handle the devices by their leads.
4
Store devices in protective foam or carriers.
5
Avoid the use of non-conductive plastics, rubber, or silk in the area where the devices are handled
6
All modules shall be packaged in materials that are anti
anti-static
static to protect against adverse electrical environments.
Avoid applications of any voltage higher than maximum rated voltages to this part. For proper operation, any VIN or VOUT should
sho
be
7
constrained to the range GND ≤ (VIN or VOUT) ≤ VCC. Unused inputs must always be tied to an appropriate logic voltage (e.g.
(e.g
either GND or VCC). Unused outputs must be left open.

Warnings
Handling Precautions: This device is susceptible to damage as a result of electrostatic discharge (ESD). A static free environment is highly
recommended. Follow guidelines according to proper ESD procedures.
Laser Safety: Radiation emitted by laser devices can be dangerous to human eyes. Avoid eye exposure to direct or indirect radiation.
