• Manufacturer Part Number: m21130
• Description: 68 X 68 3.2 Gbps Crosspoint Switch With Input Equalization
• Manufacturer: Mindspeed Technologies

21130-DSH-001-B, 3/27/03
Table 1. Terminal Functional Descriptions
Notes:
1. Higher input sensitivity and common-mode range over standard PECL.
2. Analog supplies on separate plane in packages; digital supplies do not use package planes.
3. Trig output has a voltage swing of 150 mV peak-to-peak.
4. Internal pull-up resistors on all CMOS inputs unless noted otherwise.
