• output on rising or falling edge of clock
• output on every CLKXR or CLKXR/2
• Tri-stated during inactive time slots
• sampled on rising or falling edge of clock
• sampled on every CLKXR or CLKXR/2 (see X2CLK mode)
• sampled on rising or falling edge of clock (FE select)
• rising edge determines frame start
• 8 kHz rate
• Optional CHI pin is driven low during active DX time slots
• N x 64 kHz rates, where N=4,8,16,32,48, or 64
