zl50010 Zarlink Semiconductor, zl50010 Datasheet - Page 19

• Manufacturer Part Number: zl50010
• Description: Flexible 512 Channel Dx With Enhanced Dpll
• Manufacturer: Zarlink Semiconductor

2.2
The device has 16 ST-BUS serial data outputs. Any of the 16 outputs can be programmed to deliver different data
rates at 2.048 Mbps, 4.096 Mbps or 8.192 Mbps.
2.2.1
Any ST-BUS output can be programmed to deliver the data at 2.048 Mbps, 4.096 Mbps or 8.192 Mbps mode using
Bit 0 to 2 in the Stream Output Control Registers, SOCR0 to SOCR15 as shown in Table 29 on page 65 and
Table 30 on page 66.
The maximum number of output channels is 512 channels.
2.2.2
The device offers 3 frame pulse outputs, FPo0, FPo1 and FPo2. All output frame pulses are 8 kHz output signals.
By default, the output frame boundary is defined by the falling edge of the CKo0, CKo1 or CKo2 output clocks while
the FPo0, FPo1 or FPo2 output frame pulse goes low respectively.
In addition to the default settings, users can also select different output frame pulse low cycles and output clock
frequencies by programming the CKFP0, CKFP1 and CKFP2 bits in the Control Register. See Table 2, Table 3 and
Table 4 for the bit usage in the Control Register:
