CXA1782CQ/CR
6. Sled amplifier
The sled amplifier may oscillate when used by the buffer amplifier. Use with a gain of approximately 20dB.
Sled/Tracking internal phase compensation and reference design material
Notes on Operation
1. FSET pin
The FSET pin determines the fc for the focus and tracking high-frequency phase compensation.
2. ISET pin
ISET current = 1.27V/R
= Focus search current
= Tracking jump current
= Sled kick current ($1X: PS1 = PS0 = 0)
×
Use the setting resistance within the range of 120k
to 240k
. If the resistance value is out of this range,
the oscillation may be occurred in the ISET block.
3. FE (focus error)/TE (tracking error) gain changing method
1) High gain: Resistance between FE pins (pins 6 and 7) 100k
→
Large
Resistance between TE pins (pins 12 and 13) 100k
→
Large
2) Low gain: A signal, whose resistance is divided between Pins 1 and 2, is input to FE. The internal gain
adjustment circuit is used for TE.
4. Input voltage at Pins 19 to 22 of the microcomputer interface should be as follows:
V
