TLV6722

The TLV672x are a family of devices that fully integrates the module-side INT/RSTn and LPWn/PRSn(/ePPS) circuits as defined by the OSFP and OSFP-XD MSAs. The TLV672x integrates all devices and passives for the INT/RSTn and LPWn/PRsn(/ePPS) circuits into a small-size 1.2mm x 1.2mm DSBGA-9 package. This makes the TLV672x well-suited for space-critical OSFP and OSFP-XD module designs.

The TLV672x contains integrated resistors and voltage reference that are factory-trimmed per the specifications of the OSFP and OSFP-XD MSAs, making sure that the host-to-module interface voltages and comparator switching thresholds are within the proper voltage zones.

The M_LPWn comparator within the TLV672x has a push-pull output that is capable of being powered by a separate voltage supply (M_VCC). This allows for level-shifting of host-to-module logic levels without the need of a discrete pull-up resistor. The M_RSTn comparator within the TLV672x has an open-drain output allowing for easy OR-ing of multiple reset signal drivers.

The TLV6723 and TLV6724 have an integrated clock buffer that can support an embedded pulse-per-second or reference clock signal up to 156.25MHz as defined on the OSFP-XD MSA. Whenever the M_LPWn signal is low (asserted true), the integrated clock buffer on the TLV6723 enters a self-shutdown mode, lowering the quiescent current and saving power.
