Pass D1 - What chip is U5?
I was wondering what chip U5 was in the Pass D1 service manual.
Here's the text describing the chip:
U7 and U4 along with VCO module U3 form a secondary PLL
circuit to clock the digital filter and DACís. U5 and U2 are separate
regulators for the VCO and PLL chips. R5 and R6 along with C13
form the PLL filter. When the system is locked U7 pins 3 and 14 are at the word clock rate (44.1 for cd).
