Description
The ZL40539 is a high performance laser diode driver capable of driving two separate cathode grounded laser
diodes (e.g., 650 nm and 780 nm laser diodes).
The ZL40539 contains a 150 mA low noise read channel (ChR), and three >450 mA write channels (Ch2, Ch3 and
Ch4). Each channel amplifies the positive current supplied at its reference input (INR, IN2, IN3, IN4) by a fixed
factor of 100, 250, 150 and 100 respectively.
The device is enabled with a High level applied to the Enable Pin. The read channel is activated by applying a 'Low'
signal to the ENRB pin. Each fast write channel can be enabled by applying a positive voltage difference between
the enable pins (EN2P, EN2N), (EN3P, EN3N) and (EN4P, EN4N). The output currents of the four channels are
summed together and output as a composite signal at either OUTA (if SELA select is 'High') or OUTB (if SELA
select is 'Low'). This provides the ability to drive two different laser diodes with just one ZL40539.
Voltage control of the channel reference inputs (INR, IN2, IN3 and IN4) can be achieved by using an external
resistor in series with the reference channel input to convert a given reference potential to an input current.
An on-chip RF oscillator is provided for the reduction of laser mode hopping noise. The oscillator is enabled if
OSCEN = 'High', and its output signal is added to the appropriate current output (OUTA, if SELA select is 'High', or
OUTB, if SELA select is 'Low'). The oscillator amplitude is set by external resistors from RSA or RSB to GND. Its
frequency is set by an external resistor RFA or RFB to GND. RFA and RSA are selected when SELA = ‘High’ and
RFB and RSB when SELA = 'Low'
