zl50031 Zarlink Semiconductor, zl50031 Datasheet - Page 65

• Manufacturer Part Number: zl50031
• Description: Flexible 4 K X 2 K Channel Digital Switch With H.110 Interface And 2 K X 2 K Local Switch
• Manufacturer: Zarlink Semiconductor

† Characteristics are over recommended operating conditions unless otherwise stated.
‡ Typical figures are at 25°C and are for design aid only: not guaranteed and not subject to production testing.
* Note 1: To meet the H.110 output timing requirement, the output delay time can be reduced further by programming the backplane output
* Note 2: High Impedance is measured by pulling to the appropriate rail with R
