Press Release Summary:
Model SP8110 features 2 output channels, 400 MHz on-chip adjustable oscillator, and extended temperature range of -40 to +85°C. Output channels are individually programmable up to 130 mA. High-frequency current modulation is utilized to suppress noise of grounded laser diodes. Nominal 400 MHz modulation frequency is adjustable for both channels via external resistor RF tied to ground. Power saving mode, as well as error mode, enhance application performance.
Original Press Release:
Sipex Corporation Today Announced its First Laser Diode Modulator (LDM), the SP8110
Specifically engineered for DVD video players, the SP8110 features two output channels, a 400MHz on-chip adjustable oscillator and an extended temperature range of -40C to +85C degrees. LDMs utilize high frequency current modulation to suppress the noise of grounded laser diodes. The nominal 400MHz modulation frequency is adjustable for both channels via an external resistor Rf tied to ground.
The SP8110's two output channels are individually programmable up to 130mA to operate two grounded laser diodes for both DVD and CD operation. Intelligent inputs determine which output should be driven based upon input current levels. Both a power saving mode (both inputs low) as well as an error mode (both inputs high) have been added to enhance application performance.
