Clocking for JVC XL-Z1050?

Has anyone done re-clocking for the once famous JVC XL-Z1050? Opened it up and found that it uses an 'obscure' DAC chip...seems to be JVC's very own....JCE4501...and the clock crytsal(16.xxxxMhz), with its 2 usual accompanying capacitors is located just beside this DAC chip.
Search this forum and seems like this player is very less mentioned.....and have not been successful in googling datasheets for the JCE4501 either. I need to find out which is the Xtal In pin (for the clock input) for this DAC.
