4 / 18 page Micrel, Inc. SY88232L/AL June 2009 4 M9999-063009-A hbwhelp@micrel.com or (408) 955-1690 Pin Description (continued) Pin Number Pin Name Pin Function 12 APCSET Bias current setting and control. The bias current is set by installing an external resistor from this pin to ground or using a current source. Connect a 50kΩ resistor to GND for open loop operation. 13 MODSET Modulation current setting and control. The modulation current is set by installing an external resistor from this pin to ground or using a current source. 14 BIASMAX Install a resistor between this pin and GND to set the maximum bias current for the closed loop operation. The APC loop controls the bias current up to the level of BIASMAX. When the bias current reaches the maximum value set through this pin, the driver continues to sink a current equal to this maximum. For open loop operations, this pin sets the bias current. 15 MODMON Modulation Current Monitor. Provides a current, which represents 1/100 of the modulation current. Install a resistor between this pin and GND to convert that current to a voltage proportional to the modulation current. 18 MOD- Inverted modulation current output. Provides modulation current when input data is negative. 19 MOD+ Non-inverted modulation current output. Provides modulation current when input data is positive. 21 BIAS Bias current output, sources current when /TXDIS is high. Connect to the cathode of the laser through a resistor. 22 MD Input from the laser monitoring photodiode. Connect to the anode of the laser photodiode for APC operation. 23 BIASMON Bias Monitor. Provides a current, which represents 1/50 of the bias current. Install a resistor between this pin and GND to convert that current to a voltage. 24 RSSI Received Signal Strength Indicator. Install a resistor from this pin to GND to get a voltage proportional to the received signal. 25 APCFAULT Indicates APC failure when High. Active High TTL/CMOS. Use a 10kΩ Pull up. SY88232L: Post amplifier Non-inverting input data. Internally terminated with 50Ω to a reference voltage. 27 RIN+ SY88232AL: Post amplifier Non-inverting input data. No internal termination. SY88232L: Driver inverting input data. Internally terminated with 50Ω to a reference voltage. 28 RIN- SY88232AL: Driver inverting input data. No internal termination. 30 ROUT- Post Amplifier Complementary CML data output. 31 ROUT+ Post Amplifier true CML data output. 5, 8, 16, 24, 29 GND Ground. Ground and exposed pad must be connected to the plane of the most negative potential. 17, 20, 32 Supply Voltage. Bypass with a 0.1µF//0.01µF low ESR capacitor as close to VCC pin as possible. |
