Sipex introduces new photo detector IC for 8x and 12x DVD recorders

Sipex Corporation announced its latest Photo Detector Integrated Circuit (PDIC), the SP8052. Optimized for 8x and 12x writeable DVD drives, the SP8052 features slew rates of 500V per microsecond, fast 12ns saturation recovery times, and 150MHz bandwidth.

Along with the four high speed data detection channels, four tracking channels, and two summing channels traditionally utilized for CD and DVD-write modes, two additional write channels have been specially implemented for enhanced high speed DVD write functionality. With the addition of the two dedicated write channels optimized to minimize saturation during DVD-write operations, the SP8052 enables system designers to accommodate the inevitable increase in laser power needed for higher speed writing. The device also features three selectable gain settings to adjust for variations associated with different media types and manufacturers. The PDIC is manufactured on Sipex's 10GHz BiCMOS process.

SP8052 Key Features (typical):

-- 150MHz bandwidth
-- Three selectable gain settings
-- 60dB PSRR
-- 5mV Output Offset
-- 6ns Fast Channel settling time
-- 0.5ns Group Delay
-- 12ns Saturation Recovery time
-- 500V/us Slew Rate
-- Differential Outputs with 2.7v output swing
-- 16 pin clear OPLGA packaging, 5.0mm x 4.0mm

Pricing and Availability

The SP8052 is available now and is priced at $1.65 in 100,000 piece quantities. An evaluation board is also available to assist in the evaluation of the SP8052. The product brief and additional information on the SP8052 and other Sipex product offerings may be found on the company web site at www.sipex.com.
