The transceiver is characterized for operation from –40°C to 100°C case temperatures and is available in a small footprint 4mm × 4mm, 32 pin RoHS compliant VQFN package. 6 Pin Configuration and Function RSM PACKAGE 32 PIN VQFN (TOP VIEW) Pin Functions NUMBER NAME Type DESCRIPTION Output amplitude control. Output amplitude can be adjusted by applying a voltage of AMP 16 Analog-in 0 to 2 V to this pin. Leave open when not used. BIAS 10 Analog Sinks or sources the bias current for the laser in both APC and open loop modes. Compensation pin used to control the bandwidth of the APC loop. Connect a 0.01-µF COMP 23 Analog capacitor to ground. GND 3, 6, 19, 22 Supply Circuit ground. MONB 2 Analog-out Bias current monitor. MONP 8 Analog-out Photodiode current monitor. NC 1, 9, 25 Do not connect. PD 7 Analog Photodiode input. Pin can source or sink current dependent on register setting. Disables the receiver output buffer when set to a high level. Includes a 250-k Ω pull- RX_DIS 26 Digital-in up resistor to VCC. Ground the pin to enable the output. This is an ORed function with the RXOUT_DIS bit (bit 6 in register 4). This pin is 3.3-V tolerant. Receiver loss of signal. High level indicates that the receiver input signal amplitude is RX_LOS 24 Digital-out below the programmed threshold level. Open drain output. Requires an external 4.7- k Ω to 10-kΩ pull-up resistor to VCC for proper operation. This pin is 3.3-V tolerant. Non-inverted receiver data input. On-chip differentially 100 Ω terminated to RXIN–. RXIN+ 20 Analog-in Must be AC coupled. Inverted receiver data input. On-chip differentially 100 Ω terminated to RXIN+. Must RXIN- 21 Analog-in be AC coupled. RXOUT– 28 CML-out Inverted receiver data output. 45 Ω back-terminated to VCC. RXOUT+ 29 CML-out Non-inverted data output. 45 Ω back-terminated to VCC.
