GENERAL DESCRIPTION
The SP8053 is a 10-channel photo detector IC (PDIC) designed for DVD and CD recording
applications and can operate at wavelengths of 650 and 780 nm. The device contains 20 photo
detector elements, organized into six (sensor) arrays, four of them with four identical sensors (A
– D, a – d, E1 – H1, and E2 - H2 respectively) and two with a two sensors (e, h and f, g).
Sensors A – D, E1 – H1, and E2 – H2 are used in DVD mode, and sensors a – d, e – g are
used in CD mode. The ten channels consist of four high speed channels (A, B, C, and D), four
slow channels (E, F, G, H), and two balanced differential RF channels. The high speed channel
outputs provide signals from one of the two sensor arrays (A – D or a – d), depending the
position of the media switch (Select pin). A high logic level at the Select pin selects DVD mode
(A – D sensors) while a low level selects CD mode (a – d sensors). The E - H channels output
is used for a servo control. In CD mode channels E – H provide signal from e – h sensors
respectively. In DVD mode these channels provide the signal that is sum of identically named
channels (i.e. E = E1 + E2, F = F1 + F2, etc) The RF channels output is sum of ± (A + B + C +
D) or ± (a + b + c + d) channels (depending upon Select level), with identical weights given to all
channels.
The SP8053 is manufactured with an advanced BICMOS technology.
