zl50058 Zarlink Semiconductor, zl50058 Datasheet - Page 41

• Manufacturer Part Number: zl50058
• Description: 12 K Channel Digital Switch With High Jitter Tolerance, Per Stream Rate Conversion 2, 4, 8, 16 Or 32 Mbps , 48 Input And 48 Output Streams
• Manufacturer: Zarlink Semiconductor

Figure 14, Local Port External High Impedance Control Timing (32 Mbps Mode) shows the channel control bits for
LCSTo0 and LCSTo1.
4.3
When the LORS input pin is HIGH, the Local Output Enable Bit (LE) of the Local Connection Memory has direct
per-channel control on the high impedance state of the Local output streams, LSTo0-15. Programming a LOW state
in the connection memory LE bit will set the stream output of the device to high impedance for the duration of the
channel period. See “Local Connection Memory Bit Definition,” on page 60 for programming details.
When the LORS signal is asserted HIGH, the LCSTo0-1 outputs directly the values given in LE.
