They should be connected to a low inpedance ground plane(0V). 11 Vcc I This is the power supply pin for the module. It should be connected to +5.0V. Recommended power supply decoupling. 7,9 Data & Data O There are Data output pin(Differential PECL output). Signal level of these pin are PECL level. Refer to electrical interface in NOTE4. 4,5 Clock & Clock O There are recoverd clock output pin(Differential PECL output). Signal level of these pin are PECL level. Refer to electrical interface in NOTE4. 12,14 Signal Detect & Signal Detect O When the opt ical input signal fall bellow the SD threshold level, The Signal Detect is deassert ed and its out put logic level changes form a PECL HIGH to PECL LOW. Signal Detect pin is differential PECL output pin. Refer to electrical interface in NOTE5. 10 Photo Detector Bias I This pin supplies the bias for the PI N Photo Detector and it should be connected to +5.0V. Additionally,by using Ext ernal Resistor in series with this pin, it is possible to measure the photocurrent. Refer to electrical interface in NOTE8. 17,18, 19,20 NC - These pin are No user connection and should be left open. |
