Another chip to suggest that I have used is the Texas Instruments 
CDCE913 (and family).  Wide range of input and output frequencies. If 
you have a programmer, it has on-board EEPROM.  Otherwise, it programs 
through I2S.

Start with an AC14 ST, followed by a divide by 5. I used part of a HC390 but a LS 90 will do. Take the 2 MHz output feed the input of the 570 and select 16X out comes 32 and 16 MHz. Material cost less than $ 5 regulator included.
