• Manufacturer Part Number: am79c30a
• Description: Digital Subscriber Controller ?dsc ?circuit
• Manufacturer: Advanced Micro Devices

Notes:
1. For PPCR2(0) = 0, SBIN data is sampled on the rising edge of SCLK; SBOUT data is changed on the falling edge of SCLK.
2. T1 width is eight SCLK periods.
Notes:
1. CH2STRB timing is identical to SFS timing but delayed by eight SCLK cycles.
2. This timing diagram reflects SCLK for PPCR2(0) = 0. For PPCR2(0) = 1, the diagram is identical except that the SCLK
